Yucca whipplei, also called chaparral yucca, has leaves that radiate 1 to 3 feet from its center, terminating in spikes. When blooming, the plant has a single self-pollinating flower stalk with creamy white, fragrant flowers. Yucca is hardy in USDA hardiness zones 8 and above, which means it does not do well in regions where the average winter low temperature drops below 10 degrees Fahrenheit. Knowledge of how to create the right environment for this plant will keep it healthy and blooming.
Plant Yucca whipplei cuttings or seedlings in an area with well-drained soil and full sun. The plant prefers sandy loams and becomes more hardy when you plant it in poor, sandy soil.
Water the plant, keeping it slightly moist during the growing season. Keep this up for three years so the plant can establish itself properly. After three years, rainwater is sufficient for plant growth.
Prune back dead and diseased leaves in the fall with pruning shears. Sterilize the shears with rubbing alcohol and a rag before and after use.
Provide cold protection during the plant's first winter. A cold frame will help the plant make it through.
