This Yucca forms a uniform, spiky, rounded clump of sword-like, blue-green to glaucous grey-green leaves lined with an extraordinary number of curly white filaments. Its habit is much more uniform and is overall smaller than the straight species.

Impressively stout flower scapes carry white, bell-shaped flowers in early to midsummer.
