Yes I am feeling a little dumb note to myself before you buy any seeds make sure they don't grow wild in the Mediterranean. Well how was I to know that they have been growing in my garden and I have been weeding them out. The vegetable in question is Salsify this the picture that was on the seed brochure

and in my garden I found another now I have to decide leave it in or weed it out
