Havent a clue what this might be could be a weed or maybe a flower theres a lot of it about and i don't know to keep it or not
..nice to see you about again blackest... don't know what that is... someone else might.... so...
I think it's something in the mustards/charlock etc family.
looks like everyones stumped. I even took some to the garden centre and they didnt recognise it
I think it might be winter cress (Barbarea vulgaris) or at least something similar.
It looks very similar to the green manure I grew over winter and that was mustard of some description.
I was just about to say I think it's a mustard of some kind
I agree with Barbarea vulgaris.
Thank you all for your help, I still don't know if its a keep or a dig up yet.
It will flower soon then you can decide. It's one of a large number of yellow brassica type flowers, mustard, cabbage, rape.........
It's a wildflower or weed if you don't want it. I expect the bees will like it, but if you don't then take it out.
