This stuff thrives in the muddy clay next to my creek. It grows so well there, I have to keep chopping it back to leave some room for the milkweed. In addition to butterflies, the blooms attract large numbers of bumblebees, sweat bees and flower wasps. That's great for the native pollinators, but it kind of puts the area off-limits to humans. I also find that the hairy stems irritate my skin. So a good plant, but not for areas too close to humans.

Its narrow leaves set it apart from some of the other boneset species. I got it since it was about to be thrown on the compost pile on another property - manage to coax it to grow and survive through the winter - blooming the next year after.

If you’re looking for show of color than this is not the plant for you. The fluffy white clusters of flowers bloom on top of stiff stems in late summer. They’re a dull white and not especially attractive except to our butterfly friends. It’s a close relative of the more known “Joe Pye” weed but I’d have to say not as attractive for the garden. It can grow to height of 5 ft in wet soils but remains shorter in drier conditions.
It’s a native perennial wild flower that was used as a valuable flu remedy through out history. An infusion of the leaves was acclaimed to relieve symptoms of “brakebone fever” and many other flu epidemics during the 19th century. The leaves taper to a long point and are joined at the stem opposite each other making it appear they are fused together at the bases. This suggested to the early doctors and herbalist that this plant would be useful for setting bones. They would use the leaves as a poultice to heal and promote the fusion of bones. Perhaps a load of hogwash to many of us but recent research on the plant has suggested that it stimulates the immune system and maybe someday it will become more common in the modern world of herbs.
