I first saw some uncertain rosettes locally back in March 2020. It looks like hedge mustard - but it's got some furry leaves in the centre. I was lucky enough to get some expert advice pointing me in the direction of Eastern rocket.
that hairy furriness really threw me
as it developed it looked like the eastern rocket I was more familiar with
then it developed those very long fruits so distinctive of Eastern rocket
looking back at these 2 unknown plants from March 2019 - at a place I did not find it easy to get back to, I see they were early Eastern rocket
Speaking of Brassicaceae in this road, I'm suddenly seeing both Eastern rocket and thale cress here where I haven't seen either before.
this thale cress has none of the initial basal rosette left
this thale cress still has the basal rosette
