Yucca is a genus of perennial shrubs and trees in the agave family, Agavaceae. Its 40-50 species are notable for their rosettes of evergreen, tough, sword-shaped leaves and large terminal panicles of white or whitish flowers. They are native to the hot and dry (arid) parts of North America, Central America, South America, and the Caribbean.

Yucca whipplei ssp. eremica is a synonym for Hesperoyucca whipplei ssp. eremica, a non-trunk-forming plant that forms rosettes, either solitary or with age in small groups, with very stiff blue leaves noticeably striated that are 20 cm to 40 cm long by about 2.5cm wide with a sharp tip and leaf margins that are rough to finely toothed and the underside of the leaf rough on the surface. When the plant is mature the bell-shaped white flowers are formed on stout vertical spikes 1.2 m to 2.4 m tall – after flowering this plant produces new rosettes from the base of the flowering plant, which differentiates this plant from some other Hesperoyucca whipplei subspecies. Other characteristics that distinguish this plant are its shorter, broader and stiffer leaves and thicker seed capsules. This plant comes from Baja California Norte, Mexico where it grows on flat terrain to steep ridges from 300 m to 750 m in elevation.
