Noteworthy Characteristics

Eutrochium purpureum, commonly called Joe Pye weed, is a tall Missouri native perennial that occurs in low moist ground, wooded slopes, wet meadows and thickets and stream margins throughout the State (Steyermark). It is an erect, clump-forming perennial which typically grows 4-7’ tall and features coarsely-serrated, lance-shaped, dark green leaves (to 12” long) in whorls of 3-4 on sturdy green stems with purplish leaf nodes. Tiny, vanilla-scented, dull pinkish-purple flowers in large, terminal, domed, compound inflorescences bloom in mid-summer to early fall. Each flower cluster typically has 5-7 florets. Flowers are very attractive to butterflies. Flowers give way to attractive seed heads which persist well into winter.

Genus name is derived from the Greek words eu meaning well and troche meaning wheel-like in reference to the whorled leaves.

Specific epithet means purple.

The sturdy stems are topped with 10" wide, compound corymbs of aster-type flowers with red-purple disc florets. The flowers do not have any appreciable fragrance. The blooms last from mid-summer to early fall and will persist on the plants through winter. Commonly sold at nurseries and garden centers under the name EUPHORIA RUBY. This plant is protected by patent number PP31668.
