Folklore, History, and Other Facts
Purple loosestrife was intentionally introduced into North America in the early 1800s as an ornamental, as well as accidentally by way of discarded ship ballast. It is now banned as a noxious weed in most states. (PA DCNR)
We started out as wildflowers from the bicycle trails of western Pennsylvania, but we've grown!
