This evergreen specimen is not actually a yucca, although it grows in the same conditions.  It has narrow blue-green leaves that turn purple in the winter.  Red yucca is grown for its dramatic spike of coral-pink flowers with yellow throats that appear from spring to late summer.

It works well for southwestern landscapes and as an accent.  It will tolerate a wide variety of soils, is drought tolerant, and prefers full sun.  It does not have any serious disease or pest problems.
