This White Snakeroot is a very common wild perennial in Pennsylvania and much of the East and Midwest. Its native range is from Saskatchewan through Quebec down deep into the deep South of the US, usually found growing along woodland edges. Like the other Bonesets & Thoroughworts, it is a great plant for bees, butterflies, and other pollinators when it blooms in late summer and early autumn. It can be a powerful weed in gardens and landscapes, as I have experienced, sowing itself everywhere, and it is not easy to pull out of the ground. I do like this wild native plant and think it is pretty, but I just don't want it anywhere, as it did grow unwanted in some places in a few gardens I took care of. It is sold by some native plant nurseries.
