I just discovered this species as a colony in a park in a shady area not far from a pond and creek in southeast Pennsylvania. It has a large native range through all of the continental 48 states and southern Canada from the Atlantic to the Pacific. It is a member of the Mint Family and the leaves are aromatic but are bitter to eat. Its leaves were used for making some bitter medicinal teas, but it was found out the it contains a lot of a chemical of neoclerodane diterpenoid that can cause liver damage. I think it is a pretty woodland wild flower and I was pleasantly surprised to find it. It forms colonies by spreading by rhizomes and self-sowing, so one must be careful to use it in a more natural garden. Its 2-lipped pink to pale pink flowers, typical of mints, are not fragrant, but make good cut flowers, and they attract pollinators as: long-tongued bees, hummingbird moths, and hummingbirds. Prairie Moon Native Plant Nursery sells the tiny light brown rounded seed.
