Boneset (Eupatorium perfoliatum): Insect Magnet for Moist Gardens

Boneset’s quirky name comes from historical medicinal uses, but its real superpower is supporting a thriving insect community—bees, moths, butterflies. It’s also an attractive landscape plant.

Benefits and Tolerances

Very low maintenance; great for rain gardens; insect magnet.

Seasonal Interest

Small white flower heads in summer.

Planting Time

Spring to fall; seed in fall or winter.

Distinguishing Traits

Blooms held aloft in clumps atop stems—revealing its Joe Pye Weed kinship. Fuzzy stems and leaves in spring suit tactile children’s gardens.

Design Uses

Holds its own as a specimen in cottage or prairie gardens, or formal borders. Shines in groups and massed drifts, especially as a transition between groundcovers and tall architectural grasses like Indian grass or switchgrass.

Planting Notes

Prefers consistently moist clay to loam; scorches in dry soil. Tolerates boom-bust rain cycles, ideal for rain gardens or dry creek beds. Top 10 plant for pollinator nectar. Bloom time ~1 week, but ornamental seed heads follow. Massive insect activity.
