Eupatorium perfoliatum (Common Boneset) is a robust, clump-forming perennial with erect stems boasting large flat-topped clusters, up to 8 in. wide (20 cm), densely packed with small, off-white flowers in early summer to mid-fall. Blooming for about 1-2 months, the fragrant blossoms are attractive to butterflies and pollinators in search of nectar. Pairs of long, narrow, pointed leaves joined at the base unite to surround the hairy stems. Native primarily to wet soils in low woods, thickets, stream banks, meadows, and prairies in Eastern and Southern North America, Eupatorium perfoliatum provides a wonderful garden presence and late-season flowers at a time when choices may be limited. Use it in the informal setting of a cottage garden or allow it to naturalize in prairies or meadows. Historically, the dried leaves were used to make a tonic, boneset tea, thought effective in treating colds, coughs, and constipation.
