The solitary Yucca schottii reaches heights of 1 to 3 meters. The variable rosettes are 0.3 to 0.8 meters wide. The sword-like, blue to gray leaves , 0.5 to 1 meter long, are arranged in a variable manner. The falling, dry remains of leaves cover the trunk.

The upright, branched inflorescence becomes 0.3 to 0.8 meters long. The white, spherical flowers have a length and a diameter of 2.5 to 3.5 cm. The flowering period extends from April to August.
