Native plant of rich woods. In Wildwood, occasional in the forested areas, especially on the western side and in the south, in woods near the Great Meadow.. Members of the genera Eupatorium and Ageratina with white flowers are called bonesets or snakeroots. Boneset has lower leaves that connect across the stalk and likes more open, moist areas. White boneset has narrow leaves with a cluster of small leaves at the base. Upland boneset has narrow leaves with no stalks. Sweet-scented Joe-Pye weed has pale pink flowers and leaves in whorls. Snakeroots in the genus Sanicula re completely different, unrelated plants. |
