|The 3 willow-herb species shown here have lance-shaped, nearly sessile leaves. There are 4 notched, roundish, white or pink petals and long, slender, upright, 4-sided seedpods.
This species is a downy 1-4' plant. The narrow, downy leaves are smooth-edged and the edges are often rolled under. The 3/4" pink (or white) flowers are at the tips of long, slender, upright seed capsules. Blooms July-September in moist meadows, swamps.
Hairy willow-herb (E. hirsutum) is hairy, has broader, toothed leaves. The flowers do not droop as they do in Common willow-herb (E. coloratum).
