Eastern Rocket and Oxford ragwort

Eastern Rocket

I've been looking at so many rosettes recently, especially hedge mustard and shepherd's purse. The shepherd's purse bloomed first, there are lots in bloom now and no sign of that initial basal rosette.

This particular rosette I saw on St Pancras Way (22-2-2019) which is on my walk to and from the garden centre. It's right on the pavement so obviously pretty tough. At first I thought it was hedge mustard but it is in fact eastern rocket (Sisymbrium orientale).

2 weeks later, the central stem has shot up and it has buds - and obviously NOT hedge mustard but eastern rocket

and a few days later, the buds have opened and it's in flower

everywhere seems to be being mown but this has survived as it's on the pavement away from overzealous "gardeners"

Oxford ragwort (Senecio squalidus)

I saw this in February and wasn't sure what it was. 14-2-2019

looking very groundsel-like now but I think it's Oxford ragwort

after seeing the buds and how groundsel-like it looks, I decided to look around the area further and found a similar plant in bloom nearby
