Rudbeckia subtomentosa, Sweet Coneflower

Writer's picture: ANPP VolunteersANPP Volunteers


Sweet coneflower is an herbaceous perennial in the daisy family (Asteraceae). Its foliage is low growing until it sends up a flower stalk that can be 3 to 5 feet tall. It blooms with bright yellow flowers that attract pollinators. It can bloom from June until late fall. It is native to the south-central US. The species epithet means "slightly or nearly hairy" referring to the condition of the stems and leaves. Flowers faintly smell of anise, hence the common name. 

 

Sweet coneflower prefers medium moisture, well-drained loam or sandy loam and full or partial sun. However, it's an adaptable plant and tolerates hot and humid summers, some drought, clay soil, poor soils, and is deer-resistant. It does like good air circulation and, to encourage additional blooming, you should deadhead spent flowers. It is easy to share by division. Also, the tall stalks may require some support, especially if the plant is grown in a shady area or given too much water or fertilizer. It's a good choice for rain gardens, borders, cottage gardens, and naturalized areas.
