Eupatorium perfoliatum

Common Name: Boneset

Boneset is a perennial herb that grows 2 to 4 feet tall, characterized by its unique perfoliate leaves—opposite leaves that join around the stem, giving the appearance that the stem perforates them. It produces clusters of small, white, fuzzy flowers from July to October. Commonly found in moist fields, meadows, and along shores, it prefers moist to wet soils and full sun. Historically, it was used in traditional medicine to treat fevers and other ailments, earning the name "boneset" for its use in treating "breakbone fever." In landscapes, it is valuable for wetland gardens, naturalized areas, and pollinator gardens, attracting a variety of insects.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
