Soapweed Yucca (Yucca glauca): Great Plains Native with Edible Flowers

Overview

Soapweed Yucca (Yucca glauca), also called Great Plains Yucca or Beargrass, is a stemless, clumping native of the central North American prairies. Narrow, blue-green, spine-tipped leaves form a dense rosette. In early summer, a tall spike (3–5 ft) bears bell-shaped, creamy-white, fragrant flowers. The flowers, flower stalks, and young seed pods are edible. Roots contain saponins used as soap. Extremely cold hardy and drought-tolerant, it's a keystone prairie plant. Perfect for xeriscapes, native gardens, and pollinator habitats.
