Yucca glauca (syn.Yucca angustifolia) is a species of perennialevergreen plant, adapted to xeric (dry)growth conditions. It is also known as small soapweed,soapweed yucca, narrowleaf yucca, plains yucca and beargrass.
Among the Zuni people, the seed pods are boiled and used for food. Leaves are made into brushes and used for decorating pottery, ceremonial masks, altars and other objects. Leaves are also soaked in water to soften them and made into rope by knotting them together. Dried leaves are split, plaited and made into water-carrying head pads. Leaves are also used for making mats, cincture pads and other articles. The peeled roots are pounded, made into suds and used for washing the head, wool garments and blankets.
