  • Eupatorium capillifolium

Eupatorium, also call DOG FENNEL, is a member of the Compositae (Aster) family family. There are 129 species in this genus. Eupatorium capillifolium, a perennial that grows to 6 foot tall by 2 feet wide, is in cultivation, and can be grown from either seed or cuttings in Zones 2-10. It is native to Southern United States and the Eastern United States. It flowers in spring and summer.

If grown from cuttings, the best results might be obtained from cuttings taken in early spring. Given its narrow width, one might try this in a container. It prefers regular to wet watering conditions. Grow in plenty of sun. Try arranging this with other tall narrow plants.
