Discover the beauty and biodiversity of Eupatorium perfoliatum, commonly known as Bonset or American Bonset. This American native perennial, part of the Asteraceae family, showcases flat-topped clusters of fluffy white flowers from July to September, providing an inviting haven for a variety of pollinators. Flourishing in USDA Zones 3-8, Boneset thrives in moist conditions, ideally in wet to medium-wet soils, and can grow to an impressive 4 to 6 feet in height with a 3 to 4-foot spread.
Boneset is a low-maintenance addition to rain gardens, wildflower gardens, and cottage landscapes, making it a sustainable choice for eco-friendly gardeners. Its distinctive perfoliate foliage, where leaves appear to join around the stem, adds texture and character to any garden. Though tolerant of clay and wet soils and resistant to deer, its preference for full sun to part shade and constant moisture should be noted to prevent scorching during dry spells.
Historically valued for its medicinal properties, Boneset was a staple in herbal gardens, reputedly aiding in the treatment of various ailments, including the infamous "break-bone fever." Today, it is celebrated for its ornamental allure and ecological benefits, including its role as a host plant for the Spring Azure butterfly and other species. Let the pure white blooms of Boneset elevate your garden's summer landscape, creating a vibrant and dynamic environment that supports both beauty and biodiversity.
