Eutrochium purpureum (Sweet Joe-Pye Weed)

Eutrochium purpureum is commonly called the Sweet Joe Pye Weed, one of several in the family of Joe Pye Weed. While many Joe Pyes need high moisture and sun, this species is noted for being better adapted to drier soils and has higher shade tolerance, primarily inhabiting forests and open woods. If planted in higher sun, this species will need more moisture.

Elegant in presence, this species produces large, dome-shaped clusters of pale pink to mauve-purple flowers atop sturdy, often purple-tinged stems. It blooms from mid to late summer. The foliage is arranged in whorls and emits a sweet vanilla scent when crushed—one of the easiest ways to distinguish it from other species of Eutrochium.

All Eutrochium are powerhouses for pollinators, attracting an abundance of native bees, butterflies (including swallowtails and monarchs), skippers, and hummingbirds. While not a major host plant, it does serve as a host to a number of moths.

Sweet Joe Pye is particularly useful in rain gardens, moist areas, shady pollinator plantings, and woodland gardens, where its height and late-season blooms can provide both function and beauty. Pairs well with taller species like Veronicastrum virginicum, Rudbeckia laciniata, and perennial woodland sunflowers, and woodland grasses such as Hairy Brome (Bromus pubescens) or Elymus (wild rye grasses).
