What is this plant?

I feel a bit silly asking this because I think I planted it last year, but it is not like anything I have planted before. It looks like a brassica, but what type?

Could it be some sort of mustard seed that has been grown for leaves? Or oil seed rape that has somehow found its way onto your plot? The other thing that came to mind possible rocket although I am sure they have a white flower?

I agree it's definitely a member of the brassica family.

Did you plant kale last year?  The leaves are quite large, from what I can see.

I thought I had planted kale but never found any that had survived transplant (or so I thought). I normally plant curly kale, and I had none of that last year. It might be a new variety I decided to try out, not looking like my normal perception of what kale looks like, I completely overlooked it.

Maybe it is worth picking the leaves and steaming them to try it out, before it seeds and dies.

I agree, it may be PSB. That is exactly how mine looked when I got back from a walking holiday in Scotland. The bees loved it!

Looks like Kale to me.

I'd say, #1 beans, #2 squash
