Plants 30–200 cm. Stems usually dark purple at nodes, usually otherwise greenish, rarely purplish green, usually solid, rarely ± hollow near bases, glabrous proximally, ± glandular-puberulent distally and among heads. Leaves mostly in 3s–4s(–5s); petioles 5–15(–20) mm, glabrous or sparingly puberulent, rarely ciliate; blades pinnately veined, lance-ovate or ovate to deltate-ovate, mostly (7–)9–26(–30) × (2.5–)3–15(–18) cm, bases abruptly or gradually tapered, margins coarsely serrate, abaxial faces sparingly and minutely gland-dotted and densely pubescent to glabrate, adaxial faces sparingly puberulent and glabrescent or glabrous. Heads in loose, convex, compound corymbiform arrays. Involucres often purplish, 6.5–9 × 2.5–5 mm. Phyllaries usually glabrous, sometimes sparsely hairy. Florets (4–)5–7(–8); corollas usually pale pinkish or purplish, 4.5–7 mm. Cypselae 3–4.5 mm.

Discussion
Varieties 2 (2 in the flora).
Eutrochium purpureum is morphologically variable and is known to hybridize with all other species in the genus (E. E. Lamont 1995). Historically, more than a dozen infraspecific taxa have been recognized; the extent of intergradation and the lack of correlation among varying traits tend to make recognition of more than two varieties impractical.
Selected References
None.
