Joe-Pye-Weed, Sweet/ Green-Stemmed Joe-Pye-Weed
 

Eupatorium purpureum
The solid stem of this 2-6' plant is green with a whitish bloom, and is often purplish at the bases of the leafstalks. The toothed, lance-shaped leaves are in whorls, usually of 4, and are sometimes wider than those of other Joe-Pye-weed species. The dull-pink heads of disc flowers are in a rather sparse, dome-shaped or flattish cluster at the top of the stem. Blooms August, September in open woods, thickets, roadsides.

The green solid stem, the sparser cluster of pale flowers, and the whorls of 4 leaves identify this species.
