Synonym(s): Eupatoriadelphus fistulosus, Eupatorium fistulosum
USDA Symbol: eufi14
USDA Native Status: L48 (N), CAN (N)
Trumpetweed or joe-pye weed can grow from 2-7 ft. or taller in soils that are moist through the season. Narrow, lance-shaped leaves, up to 10 in. long, are whorled along the erect stem. The huge, domed flower head is composed of several branches bearing tiny pinkish-lavender florets.
The Joe-Pye Weeds have been assigned to the genus Eupatoriadelphus to separate them from the Bonesets (Eupatorium). Some sources still refer to this species as Eupatorium. The genus Eupatoriadelphus differs from the genus Eupatorium by whorled leaves, while Eupatorium has opposite leaves.

Sow seeds in the fall and plant thickly as germination is usually low. Propagation is also possible by softwood cuttings taken in late spring or by division. Divide the plants in fall as they go dormant, or in the spring just as shoots first appear. Seed Collection:
The nutlets mature to shiny black 4-5 weeks after the flower
has faded. Only a small percentage viable; these will be plump and swollen. To collect, either take the entire
top of the plant or shake it into a paper bag. Seeds can be allowed to dry out before sowing and do not have to be perfectly cleaned. Store in a sealed refrigerated container. Commercially Avail:
If clump widens too much, divide it in fall or early spring.
