Yucca carnerosana,[1] 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.[2] The species is, however, widely distributed in northern Mexico (Coahuila, Durango, Zacatecas, Nuevo León).[3] [4] It has a wide range and is abundant, and although it has local threats, its population appears to be stable overall.
This yucca is cultivated in a few areas such as the western United States, along the lower Pacific and Atlantic coasts of the United States, in parts of southern Europe, as well as other locations.[5]
Yucca carnerosana is branched and arborescent, up to 20 feet tall, with snowy white flowers.[6]
