Summary

South Coast Research & Extension Center (South Coast REC/SCREC) is located in Irvine California, this site has a sandy loam soil and plants are irrigated with reclaimed water. UC Davis is located in Davis, California, this site has a silty clay loam soil and plants are irrigated with potable water. More information about the field sites is located in the Nuts & Bolts section.

Sandia Glow^® is a slightly smaller, more compact version of the species red yucca with long, narrow, slightly folded leaves and watermelon red blooms on long stalks that begin appearing in April or earlier in Irvine and in May in Davis. They continue to send up flowers throughout the growing season. They are unbothered by pests or disease and in Davis performed best during the hottest time of the summer even on the lowest irrigation treatment. The reclaimed water at the Irvine site may be responsible for some of the tip damage and pale foliage on many specimens there which affected the overall appearance. Where reclaimed water is not in use, this should be a reliable performer where a medium-sized succulent is desired.

No difference in growth or aesthetic measurements were observed between treatments. Since Sandia Glow produces spikes, researchers opted to record the number of bloom spikes on each replicate to assess floral quantity, rather than using the scale in the rubric. Researchers recommend irrigating Sandia Glow on low water in WUCOLS regions 2 and 3.
