Why Grow Boneset?
Boneset is an important traditional medicinal plant that also plays a valuable ecological role in the garden. Its late-season flowers support pollinators when many other blooms have faded, and its upright form adds structure to meadow, wetland, and medicinal plantings. Growing boneset at home supports conservation by reducing pressure on wild populations while deepening connection to North American herbal traditions.
