“Polk Salad here in Tennessee.”
Looks like it is toxic if not prepared properly.

Polkweed is best when very young. The stalks are very tender when less than 12” HIGH. The finger size stalks are cut and then sauteed in butter, not over cooked and is very good.
The plant can grow to 5 or 6 feet high but I don’t think it is any good after it gets big.
