Description

Yucca gigantea is a large succulent up to 30 feet (10 m) tall, with a spread up to 15 feet (4.5 m). It may have a thick, single trunk or be multitrunked resulting from a thickened, inflated, trunk-like lower base similar to an elephant's foot. The leaves are strap-like, spineless and up to 4 feet (1.2 m) long. White flowers are produced in summer, followed by brown, fleshy fruits which are oval and up to 1 inch (2.5 cm) long.

How to Grow and Care

Under the right conditions, Yucca are not difficult plants to grow. They tend to thrive on a little 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.

Yucca 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… – See more at: How to Grow and Care for Yucca.
