Additional Info

Habitat: Dry rocky woodlands, barrens, clearings, and bluffs; occasionally in more mesic, or even damp, habitats; often, but not always, on mafic or calcareous substrates. Infrequent throughout.

Wildlife value: Bumblebees are attracted to pollen. Birds enjoy the seeds particularly quail and dove. Larval host plant of various types of Sulphur butterflies. Insects like ladybird beetles, ants and flies eat the nectar at the glands found at the base of the petioles because the flowers are nectar-less.

Earth Sangha Inventory

Founded in 1997, the Earth Sangha is a nonprofit public charity based in the Washington, DC, region. The Wild Plant Nursery is the most comprehensive source of local-ecotype, native plants in the Washington DC region, and the region’s only facility dedicated exclusively to this type of propagation. “Local-ecotype” plants are propagated from local, wild, naturally-occurring populations and are well-adapted to local conditions and for wildlife species that depend on the local forms, such as pollinators. Inventory is updated on a weekly basis so number may not be accurate.
