I think this is Gray Field Speedwell (Veronica polita) spotted yesterday growing out of a pavement crack. Someone correct me if you think that is wrong.

The Pennsylvania Pellitory (Parietaria pensylvanica) should be popping out everywhere around here soon. It will grow out of anything, including tiny cracks in walls, which is a great advantage here. These shots were taken in Whitman on April 18th of last year. #UrbanBotany #UrbanFlora

Saturday, I went out to where I'd found Knawel (Scleranthus annuus) and Cutleaf Evening Primrose (Oenothera laciniata) growing together (which I now realize this is technically in Marconi East). This is what I found in the cracks.

Huge congratulations to our fabulous friend @commonbynature.bsky.social!
His #UrbanFlora of Newcastle and North Tyneside will be out on Monday.
Essential reading for everyone interested in #UrbanBotany.
It'll be interesting to read it alongside @trevorthebotanist.bsky.social's #UrbanPlants book!

I had thought that these were Acalypha virginica, but I now realize on inspection that these are Rhomboid Mercury (Acalypha rhomboidia). I have deleted a few previous posts of this population as tiny, undeveloped plants. These were shot on August 5th of last year.

One of the prettiest early-flowering pavement grasses in SE London is Fern Grass (Catapodium rigidum). This one's fl head is 3D so a candidate for subspecies majus rather than ssp. rigidum? #wildflowers #urbanbotany #pavementplants #Londonplants #grasses. #WildPavements is published 5 Mar 2026

In London for a few days a bumped into Mediterranean (Roman) Nettle Urtica membranacea in Walthamstow. Not a species I’ve seen before but unmistakable with those long linear inflorescences! #urbanbotany

Two photos: left Red Valerian, no longer upright, but lying on a tarmac pavement. Right: Ragwort. One of three or four plants in a small patch of green with trees and grass in Leicester city centre..
Too cold for flowers (and me!) today. Red Valerian (the only flower) by a pavement, and Ragwort. #WildFlowerHour #UrbanBotany

Us urban botanists aren't often put off by inclement weather. An annual tradition is a 1st Dec hunt for wild plants in flower in Deptford, SE London. Here I am in the rain on Mon checking the seed shape of Beaked Hawk's-beard, more usually in flower in London in May. #urbanbotany #urbannature

Photograph taken looking down at the deep grey tarmac against which rests a stunning yellow leaf with bronzed edges. The colour contrast is spectacular!
