Dasylirion longissimum, the Mexican Grass Tree, is a species of flowering plant native to the Chihuahuan Desert and other xeric habitats in Northeastern Mexico.[1]


Evergreen trunk-forming shrub, slow and moderate growing to 4 to 6 feet (1.2 to 1.8 m) tall and wide, and can be up to 12 feet (3.7 m) tall by 8 feet (2.4 m) in diameter. The long bladed leaves are up to 4 feet (1.2 m) long by 0.24 inches (6 mm) across.[2]


The drought-tolerant and dramatic plant is cultivated by nurseries for use in personal gardens and larger xeriscape landscape projects in the Southwestern United States and California. Dasylirion longissimum is hardy to 15 °F (−9 °C)
