Description
Yucca gigantea is a large shrub or small tree with single or several trunks topped with a rosette of spineless, strap-like leaves. It grows up to 30 feet (10 m) tall. The green leaves are up to 4 feet (1.2 m) long and 3 inches (7.5 cm) wide.
Mature rosettes produce erect, up to 3.3 feet (1 m) long stalks with large clusters of edible, pendent, white flowers in summer. The fleshy fruits are oval, brown, and up to 1 inch (2.5 cm) long.
Hardiness
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °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.
