Great Plains Native Plant Society

The Great Plains Native Plant Society is dedicated to advancing scientific knowledge and public appreciation of native plants across North America's Great Plains biogeographic region. Based in Sioux Falls, South Dakota, the organization carries forward the pioneering botanical work of Claude Barr while engaging members in field research, seed conservation, and educational initiatives. Through their flagship Great Plains Garden project—the first botanic garden devoted exclusively to Great Plains native plants—the society provides visitors with direct learning experiences about this unique ecoregion's flora, ecological significance, and practical applications. The organization fosters a vibrant community of native plant enthusiasts through annual seed exchanges, guided field trips to remote prairie regions, and an informative newsletter, making native plant conservation accessible to gardeners and scientists worldwide.
