Yucca de-smetiana, Yucca 'De Smetiana'
Yucca desmetiana is a soft leaved Yucca with usually a single-stemmed rosette when young and become multi-stemmed with age. The leaves are sword-shaped, arching, bluish-grey when young, turning burgundy as they mature (especially in winter), up to 16 inches (40 cm) long and up to 0.8 inch (2 cm) wide. It is cultivated as an ornamental in many places because of its colored foliage.

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 Yuccas 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. Repotting larger plants can be difficult, so larger plants can be refreshed with new potting soil by digging out the top 2 inches (5 cm) of the container and adding new soil. During typical repotting, remove the plant from its container and go up one container size. Always use fresh potting soil.
