Guide

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

Yucca rostrata is an arid-adapted shrub or small tree from the Chihuahuan Desert region of northeastern Mexico and Texas, with a stout trunk and stiff blue-green leaves built to store water and tolerate drought. Give it the brightest light you can, ideally direct sun, in fast-draining gritty mix, and water deeply only when the soil has dried out completely — let the top several inches go bone dry before watering again. It rots far more easily than it goes thirsty, so err toward neglect, especially in cooler months.

Toxic to cats & dogs

Saponins — vomiting, drooling. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
