Sorry to bother everyone again,but i've got another identification problem.I''ll have to stop buying these 12 perenials for 3 quid type of thing and forget to write the names down so can anyone identify please.
Yes, I agree with Bekkie - that's escaped from here
Many of the brassicas have similar flowers, but that looks very much like oilseed rape to me - brother has acres of it.
Def a brassica. All have v similar flowers so only the growth habit will tell them apart.
Having spent many hours in oil seed rape fields shooting pigeons i can confirm it is an oil seed rape plant.
Thanks all,I'll get the hang of this one day.
