This is a guide to some common weeds 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.
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.
The weeds (in alphabetical order) followed by my unknown plants and weeds at the bottom.
I've put the self-seeding plants on the Plant Identification page.
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.
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.
Here are some aquilegia in bloom.
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.
the plants with the long thin leaves amongst the chinese lanterns, not sure what variety of aster this is, one that self-seeds and looks rather weed-like, will add pics of their flowers when in bloom
aster flowers, they've taken what seems a long time to bloom, it's mid-September
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.
It can be quite long as it tangles around something, even itself. The flowers were 5.5 to 6 cm long on this one.
closer view of the leaves
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.

a close-up of the flowers
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)
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.
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.
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
here are the berries that go with the flower above
the two types of bramble leaves I've noticed
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
Bristly Oxtongue (Picris echioides)
I don't know how wide-spread this is. Unlike most weeds I've listed here, I did not see this in my garden. I saw this on holiday in West Sussex
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.
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.
yes those above are buddleja
as soon as those curved middle leaves appear, you can confirm its buddleja
This suddenly appeared, fully formed, in this clump next door. They aren't keen gardeners but I thought I would have noticed! The flowers are very thistle-like but the leaves are completely different.
this entire clump is burdock, one can clearly see it is not nearly as tall as Greater 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)
Centaurea Nigra (Lesser Knapweed)
I planted this as a wildflower but I guess in some circles it's considered a weed.
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.
Thanks to Tina who sent me this photo of 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.
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
close-up of the flower end of April 2015
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 (I will take another pic as this isn't so clear)
Cleavers, also known as goose grass. Annual, easy to pull out.
tiny white flowers of the goosegrass, below, buds just visible in the pic above
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 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.
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.
The Coltsfoot is in bloom (March 2014).
The next day the flowers are fully open.
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.
The specimen above looks so small unlike the large clump I noticed the other day.
here is a close-up of that
Common Orache (atriplex patula)
I saw this growing on the pavement outside my house. I won't pull it out until it flowers.
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.
Couch Grass. Spreads but can be pulled out at the base.
This is the couch grass flower
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.
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.
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.
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.
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
close-up of the flower on the above plant
Dyer's Rocket (reseda luteola)
seen on holiday in West Sussex
The following 3 photos are Enchanters Nightshade. Perrenial, 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.
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.
yesterday (25-9-2014) I did find an even larger fat hen
fat hen seedlings
earliest seedlings, first week
fat hen after a few weeks
and even later
I had so many of these seedlings in a seed tray I thought they were maybe something I'd planted but as they grew they became recognisable. Annual, easy to pull out.
Feverfew, a herb but it can sprout up like a weed. Easy to pull out.
Field Bindweed (see also Bindweed)
smaller than the ordinary bindweed we tend to find in our gardens, I saw this at Lordington Lavender in West Sussex, the other bindweed pictured above was in my garden
underneath side has pink stripes
Field Scabious (Knautia arvensis)
I hope this photograph shows it clearly enough for identification, the leaves at the bottom are amongst a teasel.
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.
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.
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.)
a close-up of the above plant
Geranium: Shiny Geranium or Dovefoot Geranium
At first I thought this was creeping buttercup but then saw it identified as a type of hardy geranium, two were mentioned, shiny or dovefoot. I'm not sure which this is so I'm going to see what happens, how the flower turns out, etc.
plant a month later
Goosegrass see Cleavers
I love Green Alkanet with its beautiful blue flowers in bloom very early in the spring, although some may consider it a weed. It looks similar to foxglove, just above. An easy way to tell the difference is to feel the leaves. The alkanet has stinging rough hairs whereas the foxglove is very smooth and soft. Easy to pull out.
green alkanet without its distinctive blue flowers
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.
ground elder "seedling"
I thought I had completely eradicated ground elder but found a couple little sprouts.
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.
Annual easy to pull out.
Hogweed and Hairy Bittercress, below, also see next 2 entries.
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.
The seedling is quite flat on the ground and then suddenly a stem shoots up from the centre.
hairy bittercress seedlings, before the central stem has shot up
and here is the tiniest, tiniest beginning of the hairy bittercress (about 1.2 cm wide)
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!
with the cat just to put it into perspective (it's the seedling on the bottom right)
I'm surprised I've never seen this in the garden before today (June 13th). I'm seeing this everywhere now.
It's appeared both in the garden and out.
hedge mustard flower
The following 3 photos show Herb Robert. Some people grow it as a garden plant. Personally I can't bear it 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 two images 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).
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.
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.
I don't know what makes leaves red like this, will try to find out more.
honesty seed pods, initially green they will turn brown and papery, these "coins" give the plant its other name, the money plant
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.
Horseweed (Conyza canadensis)
tall annual weed with small white flowers
I've been trying to identify this since the beginning of my quest to identify weeds and I think I've finally done it. This one was on the patio where I was staying on holiday on the southcoast so it's been getting a lot of heat and sun so it has lots of flower buds. I've got 2 growing in my garden awaitng the flowers to emerge so I could identify it and they have only smaller clumps of flowers right at the top but then they haven't been growing in the best conditions like this one. They are so tall and growing amidst other flowers they are difficult to photograph showing both the leaves and the flower buds but when at least one fully blooms I will pull them out and photograph them on their own like this one.
This horseweed grew next door very quickly. I don't know why the ones in my back garden are taking so long.
Horseweed seedlings, looking very different from the adult plant
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.
Iris foetidissima flower
Iris foetidissima seed pods
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.
tiny flowers, matt and hairy whereas the ivy-leaved toadflax below is smooth and shiny
This was taken beginning of April, when the flowers appeared. Smooth and shiny in contrast to the ivy-leaved speedwell above which is hairy.
the reddish buds before the flowers appear, below
Knotgrass, see Common Knotgrass
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.
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.
This is a moss-like weed that has appeared in some seed trays.
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.
beginning of July and I see my first mallow flower
Here is a more established plant (with lots of flowers).
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.
here's another whiligig 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.
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.
another one sprang up on the other side of the garden next door
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, Woody also known as Bittersweet
Thank you to Suzanne who identified this as Woody Nightshade. This had purple flowers and now has red berries (August 2013).
This nightshade has white flowers rather than purple. I saw it growing along Regents Canal nearby. Note the green (and black) berries on this plant.
Nipplewort, early July I see lots in flower (see example below), annual, easy to pull up
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.
here is the seedling above fully grown
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.
Orache, see Common Orache
Spreads so can be difficult to get all the parts but if traced can be easily pulled out.
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.
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.
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
another plant I sowed from seed as a wildflower but it can get invasive
Ox-eye daisy seedling
This is my first year of these self-seeding. They do look quite prolific.
Pale Smartweed, Pale Persicaria
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.
I can't remember how easy or difficult this one was to pull up. Much more developed than the one above.
Pellitory of the Wall. Large clumps which must be pulled out at ground level which can be difficult.
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.
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
Annual, easy to pull out.
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.
Below was one of my unknown weeds/plants but as it's grown I see it's a plantain (Plantago), same as the above.
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, not necessarily a weed but as it self-seeds it can pop up in the garden like a weed (in the middle, surrounded by teasel and strawberry)
and here is a poppy in flower
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
In the pic below I wanted to show how the leaves curl around the stem.
a close-up of the flower buds
the plant was small here, the first flower bud had just emerged
As the flowers die, they release seeds like a dandelion with "fluffy bits" (pappus) to carry them on the wind.
this one self-seeded between the cracks
I first noticed this prickly sow thistle in the pot with the hosta Sept 2014.
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.
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 float away!
Ragwort (Senecio Jacobaea)
I've seen this self-seeding all over the place, although funnily enough not in my garden. I was on holiday on the south coast and it was in the garden there.
(there's another weed there towards the bottom, slightly to the right)
I think I've finally found a match for this. It's difficult to say for sure as it's hard to find a really clear pic but this is a very close match from what I can see.
Smooth sow thistle (Sonchus oleraceus)
Annual, easy to pull out (do look at the seedlings below as well). 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.
There are red variations
I wasn't sure what this was at first that appeared in one of my pots but it's become clear it's smooth sow thistle.
Smooth sow thistle leaf
Smooth Sow Thistle
I suddenly noticed this smooth sow thistle (right, below) after a week away. The shorter one (left, below) was growing near it. What I found interesting is the shorter one I was able to pull out the roots but the taller one was that much more established, the stem broke off leaving the roots in the ground, so although I said smooth sow thistle was easy to pull out - it can be more difficult!
Smooth Sow Thistle seedlings
I think there's another smaller one to the right.
Here is the seedling on the left above a week later, next pic is the one on the right a week later.
a close-up of the one on the right
The following photo shows this plant just as it's developing and making it clearer it is indeed smooth sow thistle. I don't know if that is obvious from the photo but it is in person. I saw loads of seedlings like the one above recently and didn't even realize it was smooth sow thistle but I think I understand how this plant develops and changes much more now.
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.
another stinging nettle
stinging nettle flowers
this spreads like mad, I find the fruits small and often not that nice
Sweet Rocket (Hesperis matronalis)
a wild flower or a "weed", this one has self-seeded on my brick wall, I like this flower but not in this place
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.
Teasel, first year
I wasn't sure what the seedlings on the left were but the detail on the centre leaves is just beginning to show the blisters as on the larger teasel seedlings to the right so I think they are also teasel seedlings but I will leave them to see how they develop.
another creeping thistle, in bloom end of June
Thistle flowers on a spear thistle
close-up of a spear thistle before it blooms (end of June)
Tree of Heaven (Ailanthus altissima)
I've been cutting off the leaves of this tree for years. I thought I had finally killed it but I recently found this small shoot (April 2014). I had wanted to include it in my weed guide but I think I'v been too successful in eradicating it. I may have a pic of it in the background of something else (I'll check). This grows everywhere like buddleja.
mid-June I found it had grown a reasonable size leaf again, this is the sort of thing you see springing up anywhere, like buddleja
November 2014, it's regrown quite a lot by now, unless I cut if off completely (impossible because of its position by the fence) it will keep sprouting, I have cut this branch off
Verbascum thapsus (great mullein)
this is a biennial, here is the young plant, year one
Verbascum flower, year two
This is one of those "weeds" that has self-seeded in the garden.
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
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.
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)
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'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 foxglove and sweet rocket, also pictured elsewhere.
Thanks to Caroline who helped me identify this as Wild Cabbage. This was seen along Regents Canal.
most of these seedlings are willows that have self-seeded, they have a distinctive red tint (that tall one on the left is snapdragon)
a month later, end of July
in a pot across the road
I now realise I have two willowherbs: broad-leaved and short-fruited, I think I have both pictured here but will go through them and see which is which
the short-fruited is easy to pull out but the broad-leaved spreads by roots
although the willowherb flowers are usually pink, I found this one that's purple the other day
I wasn't sure what this was at first but it has grown into a willowherb.
I've left a couple of willowherbs and so far they have not grown very tall, one is 40 cm, another 70 cm and that's with lifting them up as they tend not to be very strongly upright, at least not in the shady area where mine are growing.

rosettes of broad-leaved willowherb growing from the spreading roots
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.
The fluffy bits at the top (shown below) contain the seeds.
Rosebay Willowherb has a very distinctive veining on the leaves, they don't extend to the edge of the leaf:

compare with a short-fruited or broadleaved willowherb leaf:
medium-sized plant which self-seeded last year in one of my pots, second year
I saw these, full-sized rosebay willowherb plants at the side of the road in West Sussex
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:
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.
A young wood avens some weeks later.
Some weeks later, differently shaped leaves at the top of the plant.
After the Wood Avens have flowered there are prickly burrs with the seeds.
This is very dandelion-like weed I saw growing on the south coast while on holiday but it's not a dandelion. It looks familiar but I can't remember exactly what it is. Will need to research it further. It looks similar to autumn hawkbit but I'm not sure it's that.
Same place a year later. A similar looking weed but I think the leaves are different.
is this the same as above? oval leaves with no notches
Below is a weed I found growing on the brick wall in my garden (14-1-2014). It is also rather dandelion-like.
I thought it would be difficult to pull this off but it came right off, below, with the stem breaking right off, see the "stump" on the right.
Here are two more "dandelions" I saw today (14-1-2014). Silly of me to try but I was too lazy to go get a trowel, I attempted to just pull them up. The weed on the left came right up with a complete root. The real dandelion on the right, of course wouldn't pull up, as you'd expect. The root broke off and stayed in the ground. So for that reason alone I'm sure the weed on the left is not a dandelion (it's a smooth sow thistle) and the one on the right is a dandelion.
Below, I thought it would be useful to compare the leaves on the dandelion-like weeds, left to right, a leaf from the weed on the wall above, the other dandelion-like weed I found yesterday (smooth sow thistle) above and a bog-standard dandelion.
pheasant berry (Leycesteria formosa) has been suggested, I will have to repot it and see what it produces next spring/summer
a very grass-like weed has sprung up where I was expecting seeds I'd planted, maybe it came from bird feed?
I left these for ages and nothing else happened with them. I'm still thinking something like Millet from bird seed.
