No, all I do is to mow it off. It is like carrot root. There is a thread on BYC about growing Salsify in the garden from a few years ago. I suspect that it can probably be cooked and eaten like other root vegetables. It looks like there is a bumper crop starting. Stop by if you want to harvest some to try.Have you ever used the Salsify for anything Bob? I think I've read of people making tea with it, not sure what else someone could do with it.
