Guide

The species-level account. Cultivar pages build on this and say where they differ.

A tree-form yucca native to the arid scrub and grasslands of Texas, New Mexico, and northeastern Mexico, built to store water in its trunk and tolerate drought. Give it the brightest spot you have, ideally direct sun, and a gritty, fast-draining mix. Water deeply only when the soil has dried out completely several inches down, letting it approach bone-dry between waterings.
