A rosette of long, narrow, blue-green leaves with undulating margins appears a month or so before the tall flowering stem which bears large, white, trumpet-shaped flowers resembling Easter lilies.

Conspicuous and easily seen as one drives desert roads, it seems at first glance an Easter Lily out of place. The bulbs of this species, the only one in its genus, were once used by Indians for food.
