A small, short trunked or often trunkless Yucca with very hard, thick, bluish, deeply concave leaves. It is widely distributed over northern Mexico and the southwestern United States and is found in mountain areas up to 2400 m (7900 ft.). It is extremely hardy to frost and considered to possibly being the hardiest of all trunked Yucca. Slow but easy to grow and very ornamental, it can be highly recommended for the temperate garden. It prefers a dry climate and may need some rain protection in areas with humid winters.
