- Description
-
Coastal plain Joe Pye weed is an herbaceous flowering perennial in the Asteraceae (daisy) family native to the eastern coastal plains and wetlands of North America. The Genus name is from the Greek words refering to the whorled leaves. The specific epithet is from Latin means doubtful. Joe Pye was reportedly an Indian herbalist and healer from the New England area.
This plant grows 2 to 4 feet tall in moist, fertile, and humus-rich to sandy or gravelly soils in full sun to partial shade. The leaves may scorch if the soil is allowed to dry out. You can cut the plant back to the ground in winter and it will rebound in spring. Note also that the plant spreads by self-seeding.
The large dome-shaped clusters of flowers appear in late summer to early fall and attract many pollinators.
Coastal plain Joe Pye weed works well in a meadow or naturalized area. Place it also toward the back of a bed as a mass planting or in small groups in a butterfly, cottage, native, pollinator, or rain garden.
Diseases, Insects, and Other Plant Problems: No significant problems. Good resistance to powdery mildew.
