This page is all about seaside plants, both on the beach and in the seaside garden, some plants are in both areas. Some, such as wild carrot, I've seen elsewhere but they seem so at home in the shingle I'm including them here. The saltmarsh plants are so unique, they have their own page.
Curry Plant (Helichrysum italicum)
Delosperma

Thank you to reader Ruth who's helped with an ID for this.
Seaside Daisy (Erigeron glaucus)
a popular Hayling Island plant (seen amongst the Hawk's-beard below)
Evening Primrose (Oenothera biennis)
Duke of Argyll's Tea Tree / Goji Berry (Lycium barbarum)
this is in the seaside garden on Hayling Island (July 2017) but I have seen it growing in London as well
only a few flowers left on this plant and the fruits are developing, although still green
Hedge Bindweed (Calystegia sepium)
in the dunes back from the seafront
Gazania, not sure which cultivar specifically, will research, in a seaside garden on Hayling Island

Grass-leaved Orache (Atriplex littoralis)
I saw this on Hayling Island on the south coast, July 2018

Hawk's-beard
Having another look at this, and the examples I've seen in London, and I think it's Hawk's-beard, either beaked or smooth, not absolutely certain so far. I originally saw it on the south coast but then later saw it in London so have also put it in the main Weed Guide. Perennial, in flower May to August, long bare stems rising above base rosette of toothed leaves, multiple branching flower stems from the top part of the stems. These yellow-flowered "weeds" can be quite difficult to differentiate.
I saw this a few days ago (July 9th) on Hayling Island, 2016.

close-up of the flowers, not a great pic, out of focus, but it's too far away to go back easily to take another photo
the next July, 2017, row of flowers in exactly the same place so definitely perennial
couple years later (2019) in the same place

another hawk's-beard on Hayling Island
I think these are something else, looking like giant dandelions, especially the second one, maybe that is indeed what they are?
Hoary Stock (Matthiola incana)
This was taken in May, some flowers have finished.
3 years later, another example after the flowers have finished in July.
Horseweed (Erigeron canadensis) (also see Horseweed on the Weed Identification page)
I do have this weed at home but this one is much larger than any I see at home. It was on the patio on Hayling Island so it's been getting a lot of heat and sun so it has lots of flower buds.
Hottentot-Fig (Carpobrotus edulis)
Thank you to reader Ruth who's helped with an ID for this.
Frosted Orache (Atriplex laciniata)
seafront Hayling Island, July 2018
Pelargonium? a seaside variety?
"Pink" (Dianthus plumarius) ??
not sure anything more specific
Red Valerian (Centhranthus ruber)
seaside garden Hayling Island
Rock Samphire (Crithmum maritimum)
in the seaside garden on Hayling Island, August 2019
close-up of the flowers
rock samphire and frosted orache in the shingle along the seafront, July 2018
Rosa Rugosa
seaside garden Hayling Island, but I also have this in my front garden in London
the rose hips on this rose are enormous, like fruit
Sea Beet (Beta vulgaris subsp. maritima)
a very sprawling example I saw at Eastcoke Corner on Hayling Island
sea beet close-up
Sea Campion (Silene uniflora)
Sandy Point, Hayling Island, 11-8-2019
wider view of the entire clump of sea campion on the seafront shingle
Sea Holly (Eryngium maritimum)
This is at the nature reserve at Sandy Point on Hayling Island. I don't recall seeing any before so I wonder if they planted some wildflowers there.
Sea Kale (Crambe maritima)
when I saw this sea kale (July 2018) the flowers were finished leaving lots and lots of seed pods
Sea Mayweed (Tripleurospermum maritimum)
sea mayweed on the left, a bit of frosted orache bottom right, 11-8-2019
July 2018
Sea Radish (Raphanus maritimus)
this plant has the remnants of some yellow flowers at the end of the stems in the centre on the right, seed pods on the left, August is the end of the season for this, I saw quite a few plants but this was the only one (or one of the very few) that still had flowers on it to help with identification (I didn't know it before), Hayling Island 11-8-2019
close-up of the leaves and stem (which is hairy) and some seed pods
close-ups of the seed pods
more seed pods
Sea Stock (Matthiola sinuata)
Sweet Alyssum (Lobularia maritima)
Thistle
I'm not sure what thistle this is (researching it) but it's definitely comfortable in a salty situation, growing in the shingle on the seafront, yellow horned poppy on the left
in this view the water is visible in the distance on the right
close-up of a flower
Tree Mallow
this was in the seaside garden on Hayling Island August 2019, obviously at the end of the season for this, just a couple flowers left
Viper's Bugloss (Echium vulgare)
this was in the dunes, further back from the beach July 2018
these were some spent flowers nearby
Wild Carrot (Daucus carota)
This is growing happily in seaside gardens and seafront shingle on Hayling Island, July 2017.
July 2018
in the seafront shingle, July 2018
I think this was on the dunes further back from the beach, 2018
Wild lettuce (Lactuca virosa)
(low weed at the bottom is pellitory-of-the-wall) This is in the driveway of the flat where I stay on Hayling Island, the first place I'd ever seen it (August 2015). Recently I'm seeing it in London, a lot.

Yellow Horned Poppy (Glaucium flavum)
close-up of the flower
the seed pods can be enormous, still green in this photo
those enormous seed pods, now brown
back in 2017, there weren't any yellow horned poppies to see or I wasn't looking in the right place so wasn't sure what this was
I didn't see any in bloom last year (2018) either
Unknowns
a succulent behind, buck's-horn plantain in front, buds but I won't see the flowers as I won't be back this year
a sedum / succulent I saw in the seaside garden on Hayling Island where I stay but I guess I missed the flowers this year
