General Culture:
Easily grown in average, medium to wet soils in full sun. Prefers moist, fertile, humusy soils which do not dry out. Cut plants to the ground in late winter.
Noteworthy Characteristics:
Eupatorium purpureum subsp. maculatum (formerly E. maculatum) is native to damp meadows, thickets and coastal areas in eastern North America and is commonly called Joe Pye weed. ‘Gateway’ is a popular cultivar that is more compact than the subspecies, typically growing shorter (to 4-5’ tall) and bushier with tighter and thicker inflorescences. It is an erect, clump-forming perennial that features coarsely-serrated, lance-shaped, dark green leaves (to 8” long), typically in whorls of 3-4 on sturdy, wine-red stems. Tiny, dusky rose-pink flowers in huge, terminal, domed, compound inflorescenses (12-18” diameter) bloom in mid-summer to early fall. Flowers are very attractive to butterflies. Flowers give way to attractive seed heads, which persist well into winter.
Problems:
No serious insect or disease problems. Leaves may scorch if soils are allowed to dry out.
Uses:
Tall plant for borders, cottage gardens, meadows, native plant gardens, wild/naturalized areas or water margins.
