HELP Identifying these plants (bought poppy seeds)

[unclepoppy]

I picked up some poppy seeds and this plant grew out of the batch. it looked very similar to the rest of the poppy plants as a seedling however now it looks totally different from my other poppy plants. I was hoping some forum members can help identify this plant!
I included a pic with regular poppies and I thought a pic of the stem might help with identifying..just a thought

thanks in advance!

Look like some veg seed has germinated and the plant has bolted as well. I could be very wrong. Not a poppy. Only poppy in the 3rd photo, I think!

It could be a salad brassica which has bolted

Hope our lovely @Larisa can come to your rescue!

Possibly wild mustard.
