Walking through a local park on the way home from the station today I noticed some rosettes. Veolia / Idverde is regularly spraying weedkiller in there but I don't think they've started yet this year so I'm joying the plants while I can.
catsear
nipplewort
green alkanet
hedge mustard
hawkweed oxtongue
shepherd's purse
bristly oxtongue
geranium molle
creeping thistle
lawn daisy (Bellis perennis)
salad burnett
smooth sow thistle
ragwort
black medick but
I'm not sure on this, the only thing I can think is close is horseweed but didn't know it could be so hairy
I think this is horseweed
left to right, horseweed, willowherb (small below), red valerian
I went back a couple days later to look for Eastern rocket, couldn't find any but I did find some others
wall lettuce
I think this is a dandelion but will try to keep an eye on it and see how it develops
a younger example of black medick than the other day's
red valerian
wood avens
creeping buttercup
a larger ragwort than the other day's
dock
red deadnettle, admittedly not very rosette-like, one of the few things in bloom
another in bloom, shepherd's purse
those distinctively shaped seed pods make identification of shepherd's purse easy (excuse the poor photo)
