Description
Yucca thompsoniana is a slow-growing plant with a trunk that grows up to 3.3 feet (1 m) tall, branching above the ground. Leaves are dagger-like, greenish-blue, a bit glaucous, and arranged in a rosette. They are up to 14 inches (35 cm) long and up to 0.4 inches (1 cm) wide. The inflorescence is a panicle about 3.3 feet (1 m) high. Flowers are white and up to 1.6 inches (4 cm) long. The plant blooms before there is any trunk but continues to flower after the stem begins to grow. Fruits are dry, egg-shaped capsules.
Hardiness
USDA hardiness zone 7b to 11b: from 5 °F (−15 °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 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.
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.
