Soapweed yucca is a drought-tolerant, cold-hardy evergreen perennial that forms colonies of narrow, sword-like leaves and sends up tall spikes of drooping cream-white flowers in summer. It thrives in full sun and very well-drained soil, and suits xeriscapes and dry gardens.

About
Yucca glauca (syn. Yucca angustifolia) is a species of perennial evergreen plant, adapted to xeric (dry) growth conditions. It is also known as small soapweed, soapweed yucca, Spanish bayonet, and Great Plains yucca.
Yucca glauca forms colonies of rosettes. Leaves are long and narrow, up to 60 cm long but rarely more than 12 mm across. Inflorescence is up to 100 cm tall, sometimes branched sometimes not. Flowers are pendent (drooping, hanging downward), white to very pale green. Fruit is a dry capsule with shiny black seeds.
Where it grows
Yucca glauca is native to central North America: occurring from the Canadian Prairies of Alberta and Saskatchewan in Canada; south through the Great Plains to Texas and New Mexico in the United States.
Uses
Soapweed yucca was a traditional Native American medical plant, used by the Blackfoot, Cheyenne, Lakota, and other tribes.
