Young plants of Yucca schottii have a single, unbranched trunk 20-30 cm wide and about 2-5 m tall, while older plants may have a few simple branches, or more than one trunk from the base.
The plant forms a single head, with blue-grey or gray-green rigid, straight leaves, but can sometimes be slightly curved.
The leaves are 50-100 cm long and 2.5-6 cm wide, and end in a light brown terminal spine.
The inflorescence is 40-90 cm long end held partially above the leaves, with white flowers of 2.5-5 cm long.
