Garden Weed Identification Guide

This is a guide to some common "weeds" (a lot are self-seeding wildflowers) in the average north London garden. I took the first set of photos August 2010 and have been adding to them on and off ever since. All photos were taken myself unless otherwise noted.

I don't know exactly why I like knowing the names of the weeds I find. It doesn't help control them but maybe it makes me feel more in control.

I've put the unknown plants at the bottom of the Plant Identification page - some may well turn out to be weeds/unwelcome plants but with two identification pages it makes sense to only have one unknown section. I've also moved the south coast plants/weeds to their own page. The following are in alphabetical order.


Alexanders (Smyrnium olusatrum)

I mistakenly had this as wild parsnip but a friend advised it was Alexanders, unlike many of the umbellifers this has yellow flowers, I saw this along Regents Canal, April 2017. (black horehound on the left)

Alfalfa (Medicago sativa)

Thanks to Michael for identifying this (via FB). I saw this along the Regent's Canal near King's Cross.

The following 3 images are all Annual Mercury. Last year I had it all over my front garden, as did my neighbour but after I weeded my garden and her garden well it didn't bloom and set seed so have much less this summer. Annual, easy to pull out.

Aquilegia

I include it to help those that may find it growing from self-seeding. Sometimes they get invasive and are pulled up as weeds. I like them because they bloom early before other plants have started. Annual, can be difficult to pull out - quite strong roots. Various coloured flowers.

aquilegia

Here are some aquilegia in bloom.

aquilegia

To the right of the aquilegia is a stachys byzantina, or lambs ear which self-seeds like mad so you may find it springing up like a weed in your garden.

aquilegia

Arum lily / lords-and-ladies / cuckoo-pint (Arum maculatum)

I saw these in the walled car park round the corner from me on 2-9-2017 so everything is gone but the berries and a couple of lone leaves. I see lots of petty spurge amongst them and corydalis lutea to the left. I'll have to go back in the spring and take more pics.

lords-and-ladies

Autumn Hawkbit (Scorzoneroides autumnalis)

I saw this yesterday (Sept 2nd) round the corner from me in a walled carpark which is a combination of planting and weeds in a protected environment. (we went there on the Chelsea Fringe weed walk)

the grey wood is a picnic table which this plant had to grow above to get some sun

this example is much smaller, these were only about 12 cm tall, seen August 19th southeast London

This is Morning Glory. I include it to distinguish it from bindweed which follows. They are very similar. (to the right are the Honesty seed pods)

Bindweed (see also field bindweed), white flowers similar to morning glory. Easy to pull out at ground level but must be untangled from the plant(s) it has twisted around.

bindweed

It can be quite long as it tangles around something, even itself. The flowers were 5.5 to 6 cm long on this one.

Bird Seed Weeds

Another seedling I don't recognise has appeared from the bird seed. Similar to petty spurge. April 2017

bird seed weed

I'll pot one up and see how it develops.

bird seed weed

I am now convinced this was some bird seed which got into this pot. It had been at the bottom by some of the drainage holes and I repotted it. I guess that was a mistake but I was curious.

I have had other bird seed seedlings/plants that look like grass/grain. Impossible to narrow it down and I don't I need to.

I think this is oilseed rape or some other brassica.

here is a close-up of one of the leaves above, the stem has that little leaf which looks like it should be on the larger leaf above it on the stem

looking quite like oilseed rape now

a close-up of one of the plants in the pot above

I will leave it to flower and take pics.

"Black Bindweed" can refer to tuberous Black Bryony or the annual Wild Buckwheat, each listed below. (thanks to Jacqui who explained they were 2 different plants)

Black Bryony/Black Bindweed (Dioscorea communis)

Thank you to Freda and Les who alerted me to this and provided the photos. They have read that the berries and tubers are both poisonous so beware.

Black Bindweed/Wild Buckwheat (Fallopia convolvulus)

I am sure that this came from bird seed (see above Bird Seed Weeds).

Nov 2015 I had a few self-seeding, as of April 2016 these appear to have died over winter but I will keep and eye on those pots and see if they return and hope to see flowers if they do.

May 2016 and the wild buckwheat is back.

wild buckwheat

I potted it up and it's already produced some buds a few weeks later.

wild buckwheat buds

a couple days later and the flowers are in bloom

wild buckwheat flowers

Going back to last year (10-2015), I now know that these seedlings were wild buckwheat.

I pulled up one (slightly larger about 10 cm tall) from this area recently (7-2016).

Black Horehound (Ballota nigra)

I saw this along the Regents Canal May 2017. It does look similar to deadnettle which I have loads of in my garden but haven't had this.

black horehound

black horehound

I wasn't sure what it was but the pink flowers, on some plants further along the canal, made it identifiable.

Bluebell

These may be nice in a wood but in my garden they are very annoying. They form large clumps that prevent other plants from growing. They are perennials that grow from bulbs and must be dug out. I try to do that whenever I find them. This photo was taken after this bluebell finished blooming. The stem of spent flowers is on the left.

bluebell flowers end of March (following 2 photos)

bluebell

 

bluebell leaves with ridges

 

 

when you have flowers the bluebells are easy to identify but if they haven't bloomed yet, as those below, the leaves have a ridge down the back unlike hyacinth leaves which are smooth making them easy to identify (thank you to Barbara for this info - some of us really don't want bluebells in the garden)

 

 

 

 

bluebell leaves with ridges

I wasn't sure if these were bluebells or pendulous sedge, or indeed something else. So I thought I would dig them up to be sure.

They are bluebells! with those white bulbs underground.

bluebells

Then I had a horrific thought. What if all these are bluebells as well. I sort've thought they might be hyacinths - but the hyacinths are already in bloom whereas these are all leaves. I decided to "go for it" and dig them up as well (this is my main flower bed in the sun, above is a shady less important part of the garden).

They are also bluebells, with the white bulbous roots.

Here's a bluebell with a flower coming into bloom

This is one that got away! I've been weeding them out like mad but missed this one which has gotten to be 46 cm high.

At the bottom of the stem is a new flower emerging.

Bluebells do come in different colours, white on the far left, then pink, then shades of purple and blue.

bluebell colours

also see bluebells: native or foreign invaders?

Bramble

Perennial with tough spreading roots which must be dug out and even then difficult to get all of it as it spreads so far. There are over 400 types of bramble in the UK (according to one of my wildflower books) so it makes sense I have a couple of types. The second one has finally bloomed and produced berries (it can be so difficult to ignore weeds waiting for them to flower, I've been itching to take the secateurs to them).

this is one type, in my front garden, which I think of as the usual wide-spread type of bramble, blackberry-type berries

 

here's the flower of the 2nd type in my back garden, leaves on the left in the pic below

bramble flower

here are the berries that go with the flower above

bramble berry

the two types of bramble leaves I've noticed

bramble

What I think of as the "usual" bramble has lots of fierce thorns (top stem), the other variety is tame in comparison with quite mild thorns which I can touch quite easily

bramble stems

Bristly Oxtongue (Helminthotheca echioides)

I previously only had this on my Identification - South Coast page but I saw it in southeast London yesterday (19-8-2017). Those bracts below the flowers are a distinctive feature as are the blisters on the leaves. One of the plants had very purple-red stems.

bristly oxtongue

those bumps or blisters on the leaves are a distinctive characteristic of bristly oxtongue

Buddleja. It may appear as a weed as it can self-seed and sprout up anywhere. Often seen on buildings, roofs, etc. and can cause damage, eg growing through a brick wall. Must be dug out or just cut above ground level if the roots have spread.

I'm adding another photo of a buddleja I noticed growing in the wall of a house around the corner from me. I guess the seed blew into one of the damp course holes in this wall (I assume that's what they are). This example shows how these buddleja take root anywhere.

buddleja

This buddleja suddenly appeared in the pot below..

This was taken at the beginning of March. I didn't know what it was at that time. By now (end of May) it's looking very buddleja-like (next pic).

I think these are even smaller buddleja seedlings but I will be able to confirm in a few weeks.

buddleja seedlings

yes those above are buddleja

as soon as those curved middle leaves appear, you can confirm its buddleja

Burdock

This suddenly appeared, fully formed, in this clump next door (August 2014). They aren't keen gardeners but I thought I would have noticed! The flowers are very thistle-like but the leaves are completely different.

burdock

this entire clump is burdock, I'm not sure if it's lesser or greater burdock

burdock

that clump above has long since been cleared and recently (June 2016) the lawn was mown, shortly after that this small plant appeared

I saw these yesterday (21-4-2017) off a nearby main road. I wonder how tall they'll get if left to grow.

burdock

burdock

This campanula has attractive blue flowers but I guess it might get invasive and be considered a weed. I just pulled a clump out that was smothering my lily of the valley. Here's a clump that's taken hold on my path. I will add another photo when it's in bloom.

Caper Spurge (a type of Euphorbia)

I hadn't seen a caper spurge in my garden for so long at first I didn't realise what it was. I used some home-made compost recently and I suddenly have one appearing. It's younger and fresher than the one above (which was in my first set of weed pics), it got bent so difficult to take a pic in situ so pulled it up.

about 15 cm

Cat's Ear (Hypochaeris radicata)

I saw this recently (30-7-2017) in my sister-in-law's garden in northwest London.

cat's ear

This was my original cat's ear pic from 2011 and I'll be honest, I'm not sure if it's cat's ear. At the time I didn't know as much about weeds, especially all these yellow-flowered ones. Looking at it now, I see branched flower stems which cat's ear doesn't have. It's quite mangled so difficult to say but I think it's nipplewort.

Celandine

greater celandine

saw this in east London

more of those very distinctive leaves

greater celandine

Thanks to Tina who sent me this photo of lesser celandine in her garden as I don't have any in mine. This is one of those "weeds" that some people love but others pull out as a weed.

celandine

Celery-leaved Crowfoot / Buttercup (Ranunculus sceleratus)

This was briefly in my Unknowns but thanks again to my Illustrated Book of Wildflowers (yes, a book, still a great resource) I was able to identify this. It really confused me that the leaves top and bottom were different shapes but the book confirmed that. I saw this along Regents Canal initially 30-4-2017 but just had to go back 2-5-2017 to get better pics.

celery-leaved crowfoot

the upper leaves are clearer in this pic (excuse my feet at the bottom)

celery-leaved crowfoot

the lower leaves are clearer in this pic

Centaurea Nigra (Lesser Knapweed)

I planted this as a wildflower but I guess in some circles it's considered a weed. 

centaurea nigra (lesser knapweed)

Centaurea Montana

This is really a plant identification but I wanted to put the two centaureas together so they're both here. This centaurea and the one above really do look quite similar.

centaurea montana

Charlock (Sinapis arvensis)

I'm giving the latin name for clarity as it seems to have various common names. It's funny how weeds go in cycles. I don't think I've ever had this weed before and suddenly I have a few (3 in the large pot and 1 in the small pot to the right; nb there's another plant in the middle of the large pot) and next door's garden is covered with it but I'm not sure how long that's been going on. Maybe I got the seeds blowing in from there. 

I've been waiting impatiently for it to flower and confirm its identity, the flowers have 4 petals

charlock

close-up of the flower end of April 2015

charlock flower

looking over the garden wall into next door, they have masses of charlock, taller than the wall, no wonder I have seeds from it blowing into my garden

Chickweed (Stellaria media)

Annual, easy to pull out.

Chickweed seedlings

chickweed

I got a few pots from freecycle and wanted to see what would grow, in this case chickweed!

chickweed

I let it grow and flower so I could take some clear pics

those examples of chickweed above look very lush and green but I saw some on the pavement down the road that were much more sparse, they adapted to their harsher conditions

chickweed

Chickweed, mouse-ear

in the front with buds at the top (flowering rosemary in the background)

I finally decided I had to pull it out even though the flowers hadn't opened as I really want that rosemary to thrive and not make it compete with a weed. I'm happy with the ID of mouse-ear chickweed for this.

mouse-ear chickweed

Chicory (Cichorium intybus)

Chicory is a flower I love and I have it in my garden, grown from seed but while out walking through the "wild" area of Allen Gardens in Spitalfields (East London) the other day I saw some great examples and realised it's a weed in some circles, definitely a wildflower, so should include it here to help with identification.

I wanted to show a close-up of the lower leaves

Clover

By that I mean Yellow Suckling Clover/Lesser Trefoil/Lesser Hop Trefoil (Trifolium dubium), or so I've just discovered by googling. I thought it was just Clover! It is all over most of the garden next door which I look after. I never noticed it specifically. I mean I knew there was some clover over there but not this much.

yellow suckling clover lesser trefoil

Yellow flowers seem to have taken over the garden next door. I have a lot of creeping buttercup (left, below) at the moment and wanted to compare the flower to that of the clover (right, below) although it's not the clearest pic of the clover. I'll take another but wanted to show what I have in the meantime. I've also dicovered Wall Lettuce and Hedge Mustard recently and of course, there's still the odd smooth sow thistle, nipplewort and coltsfoot, all with yellow flowers.

buttercup clover

I've been told this is Coltsfoot and possibly invasive. I've not seen it before. It suddenly appeared in the garden next door. I think I'll leave it until it flowers, presumably next spring, and see what happens and what the flowers look like. On the left is the coltsfoot, on the right a hollyhock and on the left and spreading through underneath is pellitory of the wall.

a couple weeks later, the strikingly coloured stems are more pronounced

It's quite similar to hollyhock, as noted above but worth showing ano photo (below, taken June 2014). Coltsfoot leaf is smooth and shiny, hollyhock is quite textured.

coltsfoot and hollyhock

The Coltsfoot is in bloom (March 2014).

coltsfoot

The next day the flowers are fully open.

coltsfoot

Suddenly the coltsfoot has gone mad - numerous stems and flowers, including dandelion-like  ones ready to blow seeds everywhere so I've put it straight into the garden waste bag, not even taking time for a pic before I did it in case any of those seeds got away.

coltsfoot

Comfrey (Symphytum officinale)

a purple wildflower I grew from seed

comfrey

I saw this one with white flowers in Allen Gardens, Spitalfields (East London) the other day.

Common Field-Speedwell (Veronica persica)

Apologies fellow gardeners, I had this listed as ground-ivy, a recent addition here, but those buds opened today (11-3-2017) and I was able to take a photo and it's definitely not ground-ivy but common field-speedwell, a weed I had not encountered before (first noticed it Feb 2017). It's similar to deadnettle so maybe I just didn't take note before. BTW I love those purple flowers and will not be removing it.

common field-speedwell

close-up of the flower

bare lengths of stems between groups of leaves

It happens to be growing in the same pot as some deadnettle (on the right) which I originally mistook it for as I have lots of deadnettle everywhere now (I like the small flowers, esp as the bees love them) but here it's easy to see the deadnettle has differently textured leaves which have rounded lobes. The field-speedwell leaves are smooth and toothed. (in the middle is forget-me-not and larger leaves at the top, green alkanet)

Common Knotgrass

common knotgrass

The specimen above looks so small unlike the large clump I noticed the other day.

here is a close-up of that

common knotgrass

One of the freecycle pots had common knotgrass which I allowed to grow to see the flowers produced. I didn't realize the "knots" above had the little white flowers but I hadn't taken close-up enough photos. Here are a few I took today:

Common Orache (atriplex patula)

I saw this growing on the pavement outside my house. I won't pull it out until it flowers.

common orache

I saw this common orache along the canal (middle of May 2017). I didn't recognise it at first as I've only previously seen this weed the one time above.

common orache

2 weeks later it started to bloom

another clump, in a sunnier position further along the canal, had more flowers

Corn Chamomile (Anthemis arvensis)

definitely a wildflower, not sure how much it's considered a weed, I have it from sowing some wildflower seeds from Ireland a friend gave me

lots of wildflowers have daisy-like flowers - can be confusing, I have ox-eye daisy but I know there are others

corn chamomile

Corydalis Lutea, grown as a garden plant but I pull it up as a weed as it self-seeds around my garden, including on walls, and I don't really like it. Easy to pull out.

corydalis lutea

Creeping Buttercup

If left, creeping buttercup soon spreads and gets more and more difficult to pull out. The first one below I tried to pull out with the roots but it just broke off. It was developed enough to have bloomed.

creeping buttercup flower

creeping buttercup

As below you can see these creeping buttercup have multiple stems and they make a very difficult plant to pull out but it's worth trying to get the whole clump.

Dandelion tough roots that must be dug out.

dandelions usually have toothed leaves but not always at the beginning, sometimes they develop later

Deadnettle, see Lamium

Dockweed (or just Dock)

I'm seeing a lot of this this recently whereas before I didn't seem to see too much of it. I think it has to be dug out but I haven't removed many plants. The first pic is a large plant in a neighbour's garden which is probably responsible for the seeds blowing over to our gardens.

dockweed

This second pic shows a much smaller plant (2 large leaves at the front) and interestingly some other weeds, back, right creeping buttercup, centre right stinging nettle and couch grass at the front and in the middle.

dockweed

This third image of dockweed (from another neighbour's garden) is of a plant between the other two in size.  The tall plant to the right is a teasel. - correction - reviewing this pic and knowing that later there was lesser budock there, I think that's burdock and not dock at all.

dockweed

This fourth pic of dockweed shows a close-up of the flowers and how differently shaped are the upper leaves on the plant in contrast with the large lower leaves.

small dock plant/seedling, these leaves (below) are between 3 and 6.5 cm, not very recognisable as a dockweed yet

another type of dock? (I think), still researching what kind

this is in the garden next door but I also just saw it on the pavement a few houses down the road

This is along the Regent's Canal, London NW1.

Enchanters Nightshade (Circaea lutetiana)

Perennial, easy to pull out, see below how all the roots have come out when it's pulled up but if you miss one little bit it can grow a new weed.

If you have to have a weed it's great to have one like this where the entire root comes out.

Here are the earliest seedlings of Enchanter's Nightshade.

Evening Primrose (Oenothera biennis)

I saw this in the protected environment of the walled carpark round the corner from me 2-9-2017

evening primrose

a plant still in bud

evening primrose buds

an even earlier plant which I noticed first, then the more developed buds above, then the flowers above that so I realized this is evening primrose, in isolation not sure I would have, well maybe now after I've seen these examples

Fat hen (Chenopodium album)

I found this first one today (8-9-2013) and I don't think I've ever seen a specimen of fat hen with so many flowers and so tall. I didn't measure it but it must be close to 20 cm tall.

Fat hen (Chenopodium album)

yesterday (25-9-2014) I did find an even larger fat hen

August 2017 and I have a new tallest fat hen. I saw this in Allen Gardens, Spitalfields (East London)

Feverfew, a herb but it can sprout up like a weed. Easy to pull out.

Field Scabious (Knautia arvensis)

I hope this photograph shows it clearly enough for identification, the leaves at the bottom are amongst a teasel. I planted wildflower seeds for this so not sure how wide-spread in London.

field scabiout

Forget-Me-Not, blooms very early in the spring, I guess this is next year's crop. I let them grow until they get invasive and compete with other plants then I pull them out. Easy to pull out.

Here are some forget-me-nots later in the season after they have bloomed. A weed or welcome flower, your choice.

forget-me-nots

Fox-and-Cubs (Pilosella aurantiaca)

I bought this at the garden centre as a wildflower but some may find it invasive in their garden.

fox-and-cubs

these are new plants the next year that self-seeded from my originals

fox-and-cubs

Foxglove

I grow these from seed but there are always some that sprout up unexpectedly from self-seeding as this one did. They are a wonderful flower but not if they sprout up in the wrong place.

foxglove flower

This foxglove self-seeded in my neighbours' brick wall. I love foxgloves but this one is in the wrong, potentially damaging, position.

Gallant Soldier (Galinsoga parviflora Cav.)

Saw this on the pavement nearby.

a close-up of the above plant

Garlic Mustard (Alliaria petiolata)

A reader asked me about this and suddenly I saw a lot of plants locally (end of April 2017), especially along the Regent's Canal. I've never seen it in my garden.

garlic mustard

close-up of the flower

garlic mustard

the spiky bits are the seed capsules left after the flowers are finished

garlic mustard

Reading about it, the first year the garlic mustard starts as a rosette of leaves and then grows taller and blooms in the second year. I went back to the canal and noticed a number of these small plants nearby, not that rosette-like but I still think these are the new first year garlic mustard plants.

garlic mustard first year

Geranium Molle

I saw this off  Hampstead Rd, near the railway lines out of Euston. It's in flower so quite identifiable unlike the one below which I saw in the garden next door

geranium weed

I gave up waiting for this to flower, I don't know why, the one I found above is quite pleasant, but I think this is also geranium molle.

creeping buttercup

geranium weed

Geranium Rotundifolium

I think this is geranium rotundifolium but I only saw it yesterday (14-10-2017) for the first time and I never heard of it before but the flowers do not match the other geranium wildflowers I know. It's also in bloom in October when some resources suggest an earlier finish to flowering but it seems with global warming the usual "rules" are out the window.

geranium rotundifolium

Gipsywort/Gypsywort (Lycopus europaeus)

July 2017 It has been so hot and dry and the canal quite barren. It's finally rained and this gipsywort has sprung up and bloomed.

gipsywort

this was along the canal a few months before, in April, I was hoping to see if it had flowered but it was long gone after the weeks of drought, it wasn't right by the water like the one above, I presume it is gipsywort although it's so different from the fresh bright green example above

gipsywort

Goosegrass/ Cleavers (Galium aparine)

very early goosegrass seedling

at first I didn't recognise it but as it grew and I touched it and found that dry stickiness, it became clear it's goosegrass

I love Green Alkanet with its beautiful blue flowers in bloom very early in the spring, good for bees when little else is in bloom. Don't worry if it covers the garden (as it does mine in early spring), it dies back before other plants get going. The leaves do have a similarity to foxglove but the alkanet has slightly stinging rough hairs whereas the foxglove is very smooth and soft.

green alkanet

green alkanet seedlings: on the right in the black plastic pot on the left and on the left in the terracotta pot at the bottom of the pic, compare with the textured leaves of the foxgloves: to the right in bottom terracotta pot and in the  very small pot bottom right

also in the pots below top right: dandelion along with viola and verbena bonariensis, bottom left pot: forget-me-not in the middle with that distinctive strong line down the middle of the leaf making it identifiable

green alkanet seedlings

close-up of the green alkanet seedlings from above, they have that distinctive folded 3rd leaf (and a tiny, tiny oxalis with the long thin root, in the small plastic pot bottom right above)

Grass different types

Couch Grass. Spreads but can be pulled out at the base.

This is the couch grass flower

couch grass flower

while pulling up this grass which had spread to one of my pots I noticed how red the bases of the clumps were, I never noticed that before, I'm wondering now if it is all couch grass or just a variation or detail I never noticed, will try to find out; although it's annoying I'm always happy it's relatively easy to pull out

couch grass

also couch grass or another grass? this looks quite different from the clumps above but maybe they would turn into that given time?

grass weed

some sort of grass weed, goosegrass? (not to be confused with cleavers), crabgrass?  will research further

Ground Elder. Perennial, must be dug out, including every piece of root which will grow if left. I did have it over half the garden but I don't seem to have any now after digging it out and repeating whenever I see any which is what Bob Flowerdew recommends. Eventually it weakens the plant. It took a few years but it worked.

I thought I had completely eradicated ground elder but found a couple little sprouts.

ground elder

This last pic here shows the ground elder with the roots after I dug it up. I got most of it but some definitely broke off. I'm sure it will come back but I must keep digging it up whenever I see it.

Groundsel

Annual easy to pull out.

another example

groundsel

early groundsel seedling

I saw this a few weeks ago and mistook it for horseweed but today (a few weeks later) it was a lot more identifiable. (I did take a pic but it's not as clear as the one above.)

groundsel

this has me completely confused, it looks similar to groundsel but the leaves are a different shape, ragwort? Oxford ragwort?

and just to confuse things further, a groundsel has self-seeded itself next to this (pulled it out and laid it next to this for comparison) and it is definitely different leaves at the top but similar leaves at the bottom, definitely thinking senecio weeds  (groundsel, ragwort, Oxford ragwort, not sure if there are others)

groundsel

Hart's Tongue Fern

this is one of those plants, does it go on the weed page or plant page? this and the dryopteris fern act very weed-like, this self-seeding in a wall by the Regent's Canal near King's Cross, so I think they can be acknowledged as weeds

Hart's Tongue fern

Hogweed and Hairy Bittercress, below, also see next 2 entries.

hogweed

The following is hairy bittercress. At first it's quite low-growing, a small clump on the ground (see hogweed pic above) but then the flower stems shoot up as below. Annual, easy to pull out.

hairy bittercress

The seedling is quite flat on the ground and then suddenly a stem shoots up from the centre.

with the cat just to put it into perspective (it's the seedling on the bottom right)

hairy bittercress
This is one of the oldest hairy bittercress I've seen. I've just discovered it in a pot end of March 2015. It seems to have survived the winter, which was mild and turned into an established plant - that won't last long!

hairy bittercress

Hawk's-beard

Having another look at this and the examples I've seen on Hayling Island, and I think it's Hawk's-beard, either beaked or smooth, not absolutely certain so far. In flower May to July,  long bare stems rising above base rosette of toothed leaves, multiple branching flower stems from the top part of the stems.

I noticed this mid-July locally (Camden Gardens, north London) after previously only seeing it on the southcoast and putting it on my southcoast identification page

March 2017, I notice some small plants in the same spot and think they are the new season's growth. I don't know if they are new seedlings or growing from the existing plants. Will keep a watch on how they develop. -update - they did grow and bloom but before I could take a photo they were vandalised, maybe because someone noticed me taking photos and taking an interest in them? That's a discouraging aspect of life in London.

Hedge Mustard (Sisymbrium officinale)

I'm surprised I've never seen this in the garden before today (June 13th 2014). I'm seeing this everywhere now. I pulled it up and put it on my front doorstep to take a pic. I think hedge mustard must go in phases. 2014 was a year for hedge mustard and I'm finding 2017 is as well.

hedge mustard

It's appeared both in the garden and out, the pavement outside my house.

seeing all that hedge mustard the other day made me re-consider the plant on the left which I had originally (mistakenly) called smooth sow thistle but I realise it is hedge mustard (prickly sow thistle on the right)

Herb Robert (Geranium robertianum)

The following 3 photos show Herb Robert. Some people grow it as a garden plant. Personally I can't bear it, especially the smell, and pull it out wherever I find it. Annual, easy to pull out.

And here is herb robert in bloom. Some people like it as a flower. I pull it up as a weed wherever I find it.

The following are hogweed. I collected the seed as a wildflower but not sure it's good for a small garden so disposed of it (very small hairy bittercress in the ground to the left of the pots).

hogweed

This Honesty (Lunaria), larger heart-shaped leaves) is another plant that self-seeds. I let it grow because I like it but some may pull it out. It blooms early with the aquilegia and alkanet before other plants. The dried seedheads can be seen to the right of the morning glory above. Easy to pull out.

honesty lunaria

I saw this lunaria today (18-1-2014) and thought it would be worth capturing the texture of the leaves and now that I've put the photo here I see how different the texture looks from the one above. Bottom centre here is green alkanet. The one on the right underneath is teasel. Of course, at the top is ivy.

honesty lunaria

I don't know what makes leaves red like this, will try to find out more.

Horsetail (Equisetum arvenses)

Thanks to Phil for this pic of horsetail. He has found it to be impossible to eradicate. Apparently no flowers are produced but I don't know much about this weed as, thankfully, I do not have it in my garden.

not all horseweed start with the rosette of leaves, I think it depends when they start growing

Iris foetidissima

This is another self-seeder and it can make rather large clumps. It's useful in shady areas where it's difficult to get things to grow but it can also get invasive and weed-like. Difficult to pull out.

Ivy (as a weed)

Ivy can root anywhere. If you try to cut ivy down but don't remove all the branches, they will root into a wall, brickwork, anywhere. Don't think if you cut connection to the roots, you have killed it, you haven't! I found this ivy had rooted into a bag of crushed shells I had for mulching.

Ivy-Leaved Speedwell

Joe Pye Weed (Eutrochium purpureum)

I saw this at Spitalfields Farm (East London) this week (August 2017). Thanks to Debbie, via FB, who has helped me with a better ID of this.

Lamium (deadnettle)

lamium

Thank you to Gary who alerted me to lamium. I then coincidentally saw this in my back garden. There do seem to be lots of varieties of lamium so I must look out for the flowers when they appear to confirm which type I have here which looks like a different one from that above.

lamium

the self-seeder to the right of the viola seedlings is a deadnettle

Lesser Knapweed (Centaurea nigra)

I bought this as a "wildflower" at the garden centre (they were on sale so couldn't resist) but some may have this self-seeding in their garden.

lesser knapweed

London Bur-Marigold (Bidens Connata)

This has been in my Weed Gallery (a few picturesque weed photos) for years as an unknown but I recently came across an ID. I saw this growing in the Regent's Canal near me in Camden Town, northwest London, appropriate as it spread along the Grand Union Canal network, of which the Regent's Canal is part.

London Bur-Marigold

Liverwort (Marchantiophyta)

This is a moss-like weed that has appeared in some seed trays.

liverwort

from that one small "sprout", the liverwort has spread quite a lot in my pots but it doesn't seem to cause much of a problem, recently I've noticed these upright growths

liverwort

Mallow

I read somewhere recently about this being a weed but I sowed it myself as a wildflower from seed.  I took this pic on June 11th and it's not in bloom yet. (a comparison with wood avens is below in the wood avens entry)

mallow

beginning of July and I see my first mallow flower

 mallow flower

Here is a more established plant (with lots of flowers).

mallow

This is a maple seedling. For some reason I have masses of them this spring (2012). I wasn't sure what they were, as I never noticed them before, until I found this one with the seedpod (whirligig) still attached.

maple seedling

here's another whirligig with the seedling just emerging

Here's a larger one.

This is it after I've pulled it out of the ground which gets more difficult as they get larger. I just about managed this one as the ground was wet.

Mugwort

Thank you to reader Digeroo who has identified this as mugwort There were two of these so I left one and pulled out one. I'd like to take another pic of it when it blooms.

mugwort

another one sprang up on the other side of the garden next door, the bright blue flowers are green alkanet

mugwort

mugwort flower, I don't know if this is fully in bloom or if each of the small "buds" are going to open, I sure want to catch any seeds before they're let loose so I will keep an eye on these

Nightshade, Black

white flowers and green and black (bottom left) berries, I saw this along the Regent's Canal

nightshade

I saw this in Bloomsbury this week (15-8-2016), very distinctive leaf shape as above

black nightshade

Nightshade, Woody also known as Bittersweet

Thank you to Suzanne who originally identified Woody Nightshade. I've taken a better pic of one I saw round the corner.

woody nightshade

its distinctive purple and yellow flowers (that green plant wrapping around it is something else, think maybe honeysuckle)

woody nightshade flowers

Nipplewort, early July I see lots in flower (see example below), annual, easy to pull up

nipplewort

Here's a nipplewort seedling mid-April. In my efforts to show the earliest seedlings I wanted to show this. If we can identify these very early seedlings we can weed them out before they get established, but most importantly before they set seed.

nipplewort seedling

nipplewort seedling as a rosette of leaves, I think, like horseweed, nipplewort starts with a rosette of leaves depending on when it starts growing

nipplewort seedling

this nipplewort seedling started off as a rosette flat on the ground (end of January/beginning of February 2017) and just started to grow upwards before I took this pic (on Feb 18th)

nipplewort seedling

fully grown nipplewort

At first I thought this might be Wall Lettuce, esp as I couldn't see the bottom of the plant (the flowers are very similar). I had to pull it up, to both identify it and take a photo showing it all. It became clear it's Nipplewort, with those distinctive notched leaves at the bottom. I don't usually let Nipplewort grow and see it this tall but this one got away.

Oxalis

Spreads so can be difficult to get all the parts but if traced can be easily pulled out.

oxalis

I usually pull the oxalis up whenever I see it but one plant bloomed before I noticed it and then I realised I didn't have a pic here of the flower so I've taken one. I just noticed the yellow buds on the plant above.

oxalis flower

This Oxalis (below) which I pulled up the other day (Sept 2014) shows 1. how long the roots are which did made it difficult to pull up 2. how runners extend the plant 3. a tiny bud in the middle at the top.

oxalis

this shows how oxalis puts out runners which helps it spread so much, it loves the cultivated soil in my pots but that also makes it easy to pull out

oxalis

thank you to Tom for alerting me to oxalis growing from little bulbs left in the soil under the surface

oxalis bulb

Oxalis debilis, pink woodsorrel

I thought this was just a pink oxalis weed but I see it may not be considered a weed and is generally called woodsorrel.

wood sorrel

Oxalis tetraphylla

Also called Iron Cross. We all have personal preferences on weeds, wildflowers and garden plants, this may be considered a garden plant but I would pull it up as a weed if I had it in my garden. I saw this round the corner in someone else's. (tiny herb robert seedling at the top and small rosette of (wild?) rocket at the bottom)

oxalis tetraphylla

Ox-eye Daisy
another plant I sowed from seed as a wildflower but it can get invasive

Pale Smartweed, Pale Persicaria (Persicaria lapathifolia)

This was growing in a crack on the front path next door. By pulling really hard I managed to get it up and even including the root, as shown below.

pale persicaria

I can't remember how easy or difficult this one was to pull up. Much more developed than the one above.

pale persicaria

Spotted Persicaria (Persicaria maculosa)

I saw this persicaria down by the canal, July 2017. I think it is different from the ones above but not sure as they are such poor specimens and photos (pic directly above was one of the first weed pics I took and doesn't show the top of the leaves and if they have marks like below. I hope I know better now). I found it in my weed book as Persicaria persicaria but wiki tells me that is not allowed in the latest international agreement on naming plants which I guess the book predates).

persicaria

Pellitory I've only recently realised there are two, pellitory-of-the-wall which I see quite a lot and upright pellitory which I've only seen from pots I got from freecycle.

Pellitory-of-the Wall (Parietaria judaica)

Large clumps which must be pulled out at ground level. (this is one of the first weed pics I took, must take another esp showing the buds/flowers)

pellitory-of-the-wall

Upright Pellitory (Parietaria officinalis)

This was in a pot I got from freecycle. I did not realize at the time what it was. I knew it was similar to pellitory of the wall (named pic "pellitory-type weed") but only recently came across upright pellitory.

upright pellitory

this was a pic of the sprout in the middle (cotoneaster lacteus) but it shows the upright pellitory to the left

upright pellitory

it was in another of the freecycle pots

upright pellitory

Pendulous Sedge

Small plants, surprisingly easy to pull out - until they turn into larger clumps that must be dug up. Most of the time they are just upright leaves but in the summer (?) they have catkins (not sure what else you call these). NB they look exactly like some of the nutsedge images I've seen. Unless they have the catkins or the flowers I don't know how you tell them apart.

pendulous sedge

pendulous sedge

when the sedge is small like the example on the left below it's easy to pull out but when it gets as large as the clump on the right below it needs to be dug out which I did on this clump

pendulous sedge

Petty Spurge

Annual, easy to pull out.

petty spurge

pheasant berry (Leycesteria formosa) has been suggested, I'll have to go with that as the first pic was taken a year ago (July 2014) and the second I took recently (July 2015) and it still has no flowers or the resulting berries and I'm tired of it taking up room on my patio so disposing of it
pheasant berry

pheasant berry

March 2017 this has appeared in my wall. I guess it came from the same place as the first one. I did dispose of that one above and it hadn't flowered so there must be a pheasant berry growing somewhere nearby but I haven't noticed one.

Pigweed (Amaranthus palmeri)

mid-August

on the pavement near my house I noticed these weeds, at the end of each branch there is a spray of buds, small pellitory of the wall to the right

Commonly called Plantain but the official name is Plantago, cannot be pulled out, must be dug up

Just saw this specimen today (8-9-2013) which has such well-developed flower spikes, unlike the usual scraggly specimens such as the one above.
plantain
Below was one of my unknown weeds/plants but as it's grown I see it's a plantain (Plantago), same as the above.
plantain
these are much easier to pull up if identified early, those vertically-veined leaves are distinctive, as are those flowers, shoots just visible on the right of the left plant and on the left of the right plant

Poppy

3 different types I know of

field poppy (papaver rhoeas) this is the most common one I have self-seeding in my garden

there is also the oriental poppy (papaver orientale) but I have not seen that self-seeding

Prickly Sow Thistle
not to be confused with smooth sow thistle (see below), the leaves may be the same shape (ie lobed) only prickly or more oval-shaped like this one
prickly sow thistle
In the pic below I wanted to show how the leaves curl around the stem.

and that prickly sow thistle seedling from above, leaf is about 5 cm long

prickly sow thistle seedling

I first noticed this prickly sow thistle in the pot with the hosta Sept 2014.

prickly sow thistle

The following spring (April 2015) it seems to have replaced the old leaves with this beautiful rosette of leaves. I still wanted to see it develop and bloom but also wanted the hosta so I pulled up and prickly sow thistle and put it in its own pot. It had a very large taproot, visible below.

prickly sow thistle

Beginning of June 2015 and one of the flowers has developed into a seedhead, like a dandelion, time to dispose of this before any of those seeds with "fluffy bits" (pappus) float away!

Ragwort/Tansy Ragwort (Senecio Jacobaea)

initial rosette, this is on the patio of the garden next door at the back, the one I help look after

this example I saw in my sister-in-law's garden in northwest London shows the basal rosette similar to the one above

ragwort

this is in the front garden next door (on the other side, ie not the one I look after) and I'm thinking it's Oxford ragwort as it's more sprawling and less upright than above and the examples on the bee page and South Coast page

Ribwort Plantain

(there's another weed there growing under it towards the bottom, slightly to the right, think it's a horseweed)

Rush, Soft Rush (Juncus Effusus)

oenothera on the left

I noticed a restaurant on the High St has a couple of rush plants outside it. Sadly, plants like this attract rubbish and cigarette butts but there is something that makes a business owner want to add some greenery to its frontage.

rush

The one above did flower (will find a pic). I continue to have rush seedlings appearing but now I know what they are. At first glance it looks like grass but is thicker than grass. About 2 cm tall at this point.

scrophularia grandiflora

(with thanks to the RHS forum for ID help), I don't know if this is considered a weed, think I saw it described as a such on a web site but can't find that now, I don't like it and it self-seeded so to me it's a weed!

Shepherd's Purse (Capsella bursa-pastoris)

Smooth sow thistle (Sonchus oleraceus)

Annual, easy to pull out - roots much smaller than, for example, a dandelion which has thick and deep roots. I'm afraid there are loads of pics of this but it is such a widespread weed and so common, it's worth looking at variations. As other weeds, such as prickly sow thistle and horseweed, may or may not have a well-developed rosette before the main stem shoots up, depending on when they start growing. Smooth sow thistle can have varying amounts of red from none at all to completely red.

1. starting with seedlings

the larger plant on the left has 4 leaves, the smaller plant on the right has 3 leaves and is the youngest sow thistle seedling I have

Soapwort (Saponaria officinalis)

this is in the garden nextdoor which now is only maintained by me and I like the pink flowers appearing in July so I've left it but it does spread a lot (by underground tubers I think my wildflower book said)

Stinging Nettles

Do beware of these. I have a very painful reaction to this which lasts 12 hours. I don't recall reacting so badly in the past but I've become more sensitive to it so now I wear gloves to weed it and am more careful to avoid touching it. Perennial with tough roots which must be dug out.

Storks-bill (Erodium cicutarium)

I saw this yesterday (21-4-2017) for the first time off Hampstead Rd (major road from Camden Town down to the Euston Rd at Warren St) so not sure how common a garden weed it is. I haven't seen it in my garden.

hesperis matronalis

another plant a bit closer that might be easier to see

This is a Teasel which can be a weed but I grew these as wildflowers for bees and birds. It's a biennial so I planted these last summer. First pic is flowers in bloom, next is after the seed heads have dried out and the third is a teasel plant the first year. Tough plant that must be dug out if not wanted.

as soon as that distinctive texture on the leaves is visible its identifiable as a teasel seedling, below on leaves of 4 and 5 cms, at this point its easy to pull them up if you don't want the teasels in that place, I let a few grow but not to the point where they take over, which they easily do

Tree of Heaven (Ailanthus altissima)

this is the sort of thing you see springing up anywhere and everywhere, like buddleja

I cut off the branch above and it's grown back, surrounded by jasmine (photo taken from my neighbour's garden)

Valerian (Centhranthus)

Valerian comes in red, pink and white varieties. I saw this white one recently (June 2016) at a local park in a fenced off wildflower area. I saw red valerian on Hayling Island on the south coast so it's on the Identification - South Coast page and reader Diane recently sent me a pic of her pink valerian so I'm finally pulling all this info together.

Verbascum thapsus (great mullein)

this is a biennial, here is the young plant, year one

verbascum thapsus

Verbascum flower, year two

This is one of those "weeds" that has self-seeded in the garden.

verbascum thapsis flower

at first these look similar to foxglove but then their furriness and those distinctive leaves in the center make it clear these are verbascum thapsus

verbascum thapsis seedlings

I'm a big advocate of identifying seedlings as early as possible. These are a good example. At first they could be foxgloves or hollyhocks or something else but as soon as those furry inner leaves come out (bottom right, far left), then it's definitely verbascum thapsis and if you have enough of those (or in my case too many!), you can thin them out.

It's been a couple years since I've seen any verbascum thapsis seedlings but this week I noticed this one growing out of a wall by the pavement nearby.

Vetch (Vicia)

I love these purple flowers. I grew it as a green manure next door although I don't know which specific variety. I saw this one at Spitalfields Farm (East London) the other day. Two brown teasel heads at the bottom.

Violet (Viola odorata)

These spring up lots of places, usually without the flowers which at least provide some interest. I'll try to note how long they last. April 2014 front garden. Most of the year this looks like a weed but it does flower with "violet" flowers. The thing these self-seeders that turn into weeds seem to have in common is their ability to root anywhere.

Another plant after the flowers have finished, May 2013 back garden.

Viper's Bugloss (Echium vulgare)

I guess this is considered a weed in some circles, personally I love it and planted seeds a few years ago. I don't know if this self-seeded from a seed blowing in or grew from a dormant seed in the soil. (plaintain to the right in the pic below, the soil is rock-hard so that will be difficult to dig up)

April 2017

When I first grew viper's bugloss from seed I did not have much success - think I got 1 plant - and did not take photos of the seedlings/small plants so when these seedlings appeared - or at least when I noticed them enough to take a pic (Oct 2016) I didn't recognise them but now, being impatient to find out what they are, looking around the web I think they are viper's bugloss (also foxglove, viola, snapdragon in that small pot) which I did sow seed for the previous few years but never seemed to get any germination.

a reader suggested fox and cubs so I compared the two, fox and cubs to the left and above of the pot, similar in having rosette of hairy leaves

Wall Lettuce wall lettuce


This is so much like smooth sow thistle but the flower is definitely  different although the lower leaves are quite similar. It's quite tall. This one was 85 cm tall - thus the difficutly of taking and posting the photo.

 

 

 

 

 

 

 

 

 

 

 

 

 

This photo below was taken when the wall lettuce was in situ in the flower bed. I had to pull it out to show the entire plant.

I had previously taken this photo of the small plant in this spot. I thought it might have been nightshde but know I can see it was wall lettuce.

I previously had this as a smooth sow thistle but I'm now thinking it's wall lettuce, although as I didn't let it develop any further I can't say for sure.

smooth sow thistle

Here's another plant I initially thought was smooth sow thistle round the corner (pellitory of the wall to the left) but I now think is wall lettuce, see close-up of the buds next pic.

the buds are looking more wall lettuce, I will see how they develop

Wall Weeds

I've noticed recently how some weeds are so adept at seeding in a wall, which helps them be so annoying. Below are pellitory-of-the wall (back) and corydalis lutea (front), both of which I picture elsewhere. Also sprouting in walls recently are buddleja, foxglove, verbascum thapsis and sweet rocket, also pictured elsewhere.

White Campion (Silene latifolia)

I saw this along Regents Canal yesterday (16-5-2017). I guess other times I've walked there it wasn't in bloom.

white campion before it blooms, the flowers make it identifiable, without them nearby I'd never know what this was

Wild Cabbage

Thanks to Caroline who helped me identify this as Wild Cabbage. This was seen along Regents Canal.

Willow

most of these seedlings are willows that have self-seeded, they have a distinctive red tint (that tall one on the left is snapdragon)

Willowherb generally 2 types in our gardens:

broad-leaved willowherb shiny bright-green leaves of classic shape, spreads via roots which emerge as rosettes on the surface of the soil, difficult to pull up if part of a spreading root system

short-fruited willowherb thinner leaves, easy to pull up

In the countryside, there is also Rosebay Willowherb. I've never knowingly seen it flowering in a London garden but I have seen them in flower outside urban areas. Having said that, I think it's growing next door but so far not large enough to flower. - update - pretty sure I've seen it flowering nearby last year (2016) but will check and take a pic this year (2017)

Short-fruited willowherb, the fluffy bits at the top, just starting to show below, contain the seeds.

although the willowherb flowers are usually pink, I found this one that's purple the other day

Broad-leaved willowherb, by the time I noticed this it's grown multiple stems

I noticed some broad-leaved willowherb plants in the back garden and when I pulled them up saw two different sprouts on the roots, red leaved (top below) and green (below in the pic below) and then close-ups of each in the following pics.

I think this is broad-leaved but I'm not even sure. At this stage it looks as if it could be either.

Rosebay Willowherb

That (on the left above, taken beginning of March) has turned into this, middle of June.

3 months later the above has grown a little taller but otherwise little change.

and here's another pic, I wanted to make sure that red stem showed up clearly (the nigella has a red stem as well)

Rosebay Willowherb has a very distinctive veining on the leaves, they don't extend to the edge of the leaf:

This is Wood Avens also called Herb Bennett (Geum Urbanum). I wasn't sure if it was a weed or a plant but apparently it has an RHS AGM (for those that like it, personally I hate it). I think it has a yellow flower. I haven't let one bloom for a while. I'll leave one and take a pic of the flower. Easy to pull out at the base. Taken in April, before it flowered:

wood avens

I noticed today (mid-June) that the wood avens were in bloom The following 3 photos show the wood avens flowers.

One thing I've recently realised about wood avens is that the young, first leaves at the bottom of the plant are differently shaped from the older leaves at the top. I guess I thought all the leaves on a plant were one shape. Realising this helps in identifying weeds. I didn't realise that the plant below and the plant above are both wood avens but obviously the leaves are completely different.

After the Wood Avens have flowered there are prickly burrs with the seeds.

I wasn't sure if the plant on the right was wood avens or mallow, then saw I have them both near each other so thought a comparison might be useful, mallow on the left, wood avens on the right

Yarrow (Achillea millefolium)

I don't know why I hadn't seen this before in London until this week. I did see it on Hayling Island (see Identification - South Coast). This was in Allen Gardens, Spitalfields (East London).
