This plant is fast growing to about 6'-10' tall and 8'-13' wide. Wide gray leaves have stiff terminal spines and recurved teeth on margins. It prefers full sun and well-drained situations. After blooming, which could take several years, it will die but will send up new pups from around the base. Some people are allergic to the sap. Removal is difficult if unwanted.

Common name:Red Yucca
Botanical name:Hesperaloe parviflora

This spectacular succulent is wonderful for a desert garden, with rosettes of gray green leaves to about 3'-4' tall and 6' wide. Red flower stalks emerge during spring and remain on the plant until the end of summer. This shrub will spread to form a crowded grass-like clump. This evergreen shrub is drought resistant but will appear better and bloom longer with added moisture. It does well in full sun, reflected heat, poor soils and cold temperatures to at least 0 degrees F.
