Dasylirion is a genus of 17 species of grassy looking rosette plants in the family Ruscaceae, all native to northern Mexico, with three species also extending into the south-western United States. They are not grasses but are related to the Agaves. As they grow older, the bases of several species develop into a beautiful trunk. When the plants are mature they send out blooms with hundreds of greenish-white bell-shaped flowers on a tall narrow spike coming from the center of the plant. Unlike most Agaves they do not die after blooming. Most Dasylirion species are reasonably resistant to cold and drought.

Dasylirion acrotrichum commonly known as the Great Desert Spoon, Spoon Yucca and Green Sotol is a plant native to the Chihuahuan Desert and other xeric habitats in northern and central Mexico. The foliage is firm narrow bladed leaves up to 100cm long, grass like and 1cm across, symmetrically radiating in a rosette, 180 cm tall by the same in diameter, from a central core that elongates into decumbent trunks. The mid-Summer flower spike of small white flowers is 1.8 to 4.6 metres tall. The drought-tolerant and dramatic plant is cultivated by nurseries for use in personal gardens and larger xeriscape landscape projects. Dasylirion acrotrichum is hardy to 7 °C!
