Shaggy Rosinweed (Silphium mohrii)
Aster FamilyShaggy Rosinweed is an uncommon native with a range restricted to TN, GA, and AL. This sun loving, drought tolerant wildflower makes an excellent addition to prairie landscapes and pollinator gardens. During late summer, each stem bears multiple butter yellow flower heads that will support bees, butterflies, and other native insects, while autumn seed heads provide a food source for birds and continued visual interest in the garden. Leaves and leaf structure are covered with dense, bristly, silver hairs that add considerable texture and structure to the garden environment. It does not have an aggressive nature like many members of the Silphium genus. It is considered rare across its native range due to habitat loss and fragmentation. It is typically found in prairies, meadows, roadsides, and woodland edges. Promoting this plant in native landscapes supports regional conservation efforts by increasing its presence in the cultivated environment.
