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.
