Yucca gloriosa is a relatively slow-growing shrub or a small tree, usually solitary or rarely with several stems arising from the base and topped by a cluster of stiff sword-like glaucous-green leaves. It grows up to 8 feet (2.4 m) tall. Leaves are linear, usually with smooth or rarely finely-toothed margins and a pointed tip. They are up to 20 inches (50 cm) long and 2 inches (5 cm) wide.
The flowers are bell-shaped, creamy-white, sometimes tinged with red or purple, and appear in late summer arranged in a panicle borne on an up to 4 feet (1.2 m) long stalk with the lower portion resting among the leaves. Fruits are leathery, elongated, 6-lobed, and up to 3.2 inches (8 cm) long berries.
USDA hardiness zone 7a to 11b: from 0 °F (−17.8 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Under the right conditions, Yuccas are not difficult plants to grow. They tend to thrive on a bit of neglect rather than too much attention. They are especially easy to overwater, and soggy stems are a sign of too much water. The best conditions for Yucca include a sunny corner with relatively low humidity. They are not prone to many pests, although scale can be an issue. Over time, plants will typically lose their lower leaves (in nature, they droop, forming a skirt around the trunk), giving the plant a pleasant "tree-like" appearance.
Yuccas are relatively slow-growing plants that should only need to be repotted every other year. They do well, slightly pot-bound, as long as they don't become heavy enough to tip over their containers.
