Description

Tall Joe Pye Weed (Eutrochium fistulosum) is a tall native perennial which uncommonly occurs in low moist ground, wet meadows, wet thickets and stream margins. It is an erect, clump-forming perennial which typically grows 4-7 feet tall and features coarsely-serrated, lance-shaped, dark green leaves (to 12 inches long) in whorls of 4-7 on sturdy green stems which are hollow. Tiny, vanilla-scented, dull pinkish-purple flowers in large, terminal, domed, compound inflorescenses (12-18 inches diameter) bloom in mid-summer to early fall. Flowers give way to attractive seed heads which persist well into winter.

The blooming period occurs from mid-summer to early fall and lasts about 1 month. Afterwards, the disk florets are replaced by small bullet-shaped achenes (about 3 mm. long) with tufts of bristly hair. They are distributed by the wind. The root system is mostly fibrous, although sometimes rhizomes are produced.

Habitats include wet sand prairies, seeps and springs in partially wooded areas, soggy thickets, fens, rocky sandstone ravines along streams, and low areas along railroads and roadsides. Sometimes this wildflower is cultivated in gardens, although many cultivars display some evidence of hybridization.

Easily grown in average, medium to wet soils in full sun to part shade. Plants prefer moist, fertile, humus-rich soils which do not dry out. Best in full sun. Tall stemmed plants are more likely to need support in part shade locations.
