Eutrochium perfoliatum (Boneset)

One of the most historically significant native wildflowers, boneset's opposite fused leaves make it instantly identifiable, and its nectar draws a wide range of pollinators right through the heart of summer - a genuine wetland-restoration staple with deep roots in traditional medicine.

Species Overview

Eupatorium perfoliatum is a hardy perennial wildflower native to North America, thriving in wetlands, marshes, and damp meadows. It grows 3 to 4 feet tall and is easily identified by its opposite leaves that appear fused around the stem, giving the plant its "perfoliate" epithet. Flat-topped clusters of small, white flowers bloom from mid to late summer.
