Oh, and they dont taste like artichokes at all. Not even in the same family. They grow like weeds, so if you actually plant them, a tall ( 7, 8 feet) stalk will form, similar to a sunglower. But , the flowers will only be about the size of a black eyed susan. But then the next year, u will have 10 times as much as u started with . and u can dig them up through out the winter as u need them ( assuminig someone provides us with something to do with them ). But as i said, like mint, or horse radish.... they will take over your yard, so if u get the desire to try and plant them , keep this in mind
