Very attractive blue-gray to blue-green yucca growing up to 6-15 feet tall (occasionally much larger). From southwest Texas (Brewster County) and northern Mexico. Relatively long leaves (up to 2 feet) appear in great numbers (>100) in a healthy rosette. Leaves are smooth, with a terminal spine and very fine marginal teeth. They sometimes have a yellow marginal stripe. Dead leaves are retained below, pointing downward and cloaking the stem. Many/most plants are unbranched, but they may branch sparsely at the base or at the top. White flowers appear in spring on inflorescences to 2 feet or more tall.

The dense, full foliage atop a relatively narrow stem (6-12" wide) makes older plants particularly impressive. Some people choose to remove the dead leaves below the rosette by cutting them off at the base, leaving a sort of nubbly stem exposed. I prefer the natural look.

Provide lots of sun and excellent drainage in containers and in the garden.

Compare to Y. thompsoniana (found further north in Texas; shorter; smaller leaves with a rough texture) and Y. rigida (from northern Mexico; fewer, wider leaves that are rigid and straight; inflorescence partly cloaked by leaves).
