Description

Eutrochium dubium grows 2 to 5 feet tall. It may be distinguished from other species of Joe-Pye weed by its leaves, which narrow abruptly at the base, rather than taper gradually. Also, the stems bear fine purple spots and the purplish pink flower clusters are dome-shaped, rather than flat-topped as with other species.

Cultivation

The relatively small size of this species of Joe-Pye weed (up to 5 feet), make it well suited for garden settings. It is a moisture loving plant that will withstand occasional flooding. It thrives with "wet feet" and care should be taken to not let the soil dry out for long periods. Eutrochium dubium enjoys a long bloom period, that can begin as early as July, and extend well into October. Zones 5-8

Propagation

Propagate by root division of mature clumps in spring when the first new shoots appear or in fall when the plant goes dormant. May also be propagated by softwood cuttings or from cold stratified seeds.

Additional Notes

The nectar rich flowers of coastal plain Joe-Pye weed will attract a great variety of pollinators. "Little Joe" (as it is also known) is a great plant for use around water features, where it will provide interest late into the growing season.
