description

The Yucca torreyi , which grows solitary or with several trunks , reaches a height of up to five meters. The rough, yellow to green, fibrous 0.3 to 1 meter long leaves are arranged variably.

The upright, branched, dense inflorescence that begins between the leaves is 0.5 to 0.8 meters long. The spherical to bell-shaped variable flowers have a length of 3.5 to 7.5 cm and a diameter of 0.6 to 1.8 cm. The six identical bracts are cream-colored and purple-colored at the base. The flowering period is from March to May.
