YUK-ah
Agavaceae
These adaptable plants are indigenous to North and Central America and the West Indies. They are grown for their decorative, sword-like leaves that vary in rosette form, leaf width, shades of green or blue, and variegation. They produce very large spikes of hanging bell-shaped flowers that are most often white. They are ideal for containers, desert gardens, gravel gardens, or rock gardens, where their silouettes stand out; also grow in mixed borders, where their forms contrast against a softer backdrop. Some of the tender species form massive specimens.
Noteworthy characteristics:  The bold lines of these rosette-forming plants make an architectural statement in both formal and naturalistic garden settings.
Care:  Widely adaptable to different light, soil, and moisture conditions. Yuccas grow best in full sun to partial shade in rich, evenly moist soil. Tender species grow well under glass.
Propagation: 

Remove rooted suckers in spring. Take root cuttings in winter.
