This is one of my favorite wild vegetables, and tastes one heck of a lot better than its relative salsify. Young stems/flower buds are edible once steamed. Studies of this species for use as an alternative vegetable crop do exist.
Yes, they are "weedy," but they're terribly difficult to transplant to one's garden. The flowers are quite beautiful, and the seed heads (achenes) are very pretty. When cut, stems release a sticky latex (so be prepared to scrub your fingers).

I like this plant. Yes, it's probably considered a "weed" by most people, but I find the "puffballs" amazing! Their like the common dandelion's on steroids! Try imagining a softball on a stick, and this is what you end up with! The huge, yellow flowers are a great bonus as well!
