Yucca angustifolia) is a species of perennial evergreen plant, adapted to xeric (dry) growth conditions.

[5][6] 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.

[7][8] The "honey ant" (Myrmecocystus mexicanus), among other species, has been observed collecting nectar from Y. glauca.

[13] If this exhausts her load of pollen she then goes to gather more before moving on again to investigate more flowers as potential sites to lay more eggs.

[12] Soapweed yucca was a traditional Native American medical plant, used by the Blackfoot, Cheyenne, Lakota, and other tribes.

[16] The peeled roots are pounded, made into suds and used for washing the head, wool garments and blankets.

[19] Yucca glauca is desirable as a landscaping plant, particularly for low water and high altitude gardens.
