Eupatorium perfoliatum 5-7' tall. Also called Thoroughwort. Majestic North American native with flat-topped clusters of creamy-white to milky-lavender flowerheads atop fuzzy upright stems with deeply veined dark green diamond-shaped perfoliate leaves.
Traditionally used to alleviate the symptoms of “breakbone fever,” a highly infectious disease known to cause extreme fever and aching pain that travels deep into the bones—hence the name boneset. Tincture of the flowering tops and leaves induces sweating, stimulates the immune system and acts as a mild anti-inflammatory. North American Indians and early colonial settlers administered boneset tea during flu epidemics, and its common use continued well into the 20th century.
Peak bloom is mid to late August, providing a generous late-season supply of nectar for adult butterflies and other pollinating insects. Boneset is a practical and fetching addition to the wilder part of the orchard and perennial border.
Plant 3' apart in moist soil and full sun to dappled shade. MOFGA-certified organic, grown at Ripley Farm. Z3. Maine Grown. (bare-root crowns)

These plants have long histories of traditional medicinal use. It’s up to you to educate yourself about the safety and efficacy of using plants for medicinal purposes. The statements in our catalog regarding traditional medicinal uses of plants have not been evaluated by the FDA. The plants we sell are not intended to diagnose, treat, cure, or prevent any disease. Plants may take a year or more to establish before they flower; roots often take several years to reach harvestable maturity.
When you receive your order, open the bags and check the stock. Roots and crowns should be firm and pliable. If they are slightly dry, add a little water or, if they are going to be potted up soon, wet the roots. Generally, a little surface mold is harmless and will not affect the plant’s future performance. If you cannot pot them up immediately, store them in a cool (35–40°) location for a short time.
Do not plant bare-root perennial plant crowns directly outdoors.
Pot up the rootstock using well-drained potting mix in a deep 6" pot or a 1-gallon container. Avoid coiling the roots in under-sized containers. Grow newly potted perennials for a few weeks in a protected location in indirect light at 50–60°. Wet and/or cold conditions for an extended period may cause rotting. Transplant outside once they show some top growth and the danger of frost has passed.
