This trunk-forming variety of yucca is native to the rocky hillsides of the Chihuahuan Desert. Blue tree yucca is generally seen with one trunk, but it occasionally branches to form multiple trunks. Powder blue sword-shaped leaves with thin yellow margins gather in rosettes at the top of each stem, and a stalk of creamy colored flowers emerges from the center of each rosette in late spring and early summer, followed by woody seed capsules.
As older foliage dies, it lays flat against the trunk, forming a shaggy, straw-colored thatch that is often referred to as a skirt. This skirt can be left on the trunk, or removed for a more manicured appearance. Blue Tree Yucca makes a statuesque accent in low water landscapes, courtyards, and even in containers!
