Yucca carnerosana,[3] commonly known as the giant Spanish dagger, is a species of North American plant in the asparagus family that grows in arid and desert climate areas.

In the United States, it is confined to only a few counties in western Texas, where endemic populations are found in rocky outcrops.

[4] The species is, however, widely distributed in northern Mexico (Coahuila, Durango, Zacatecas, Nuevo León).

[5][6] It has a wide range and is abundant, and although it has local threats, its population appears to be stable overall.

[7] Yucca carnerosana is branched and arborescent, up to 20 feet tall, with snowy white flowers.
