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.
The performance of the 80% treatment of the Cool Glow Lime was significantly better than the 50% and 20% treatments, with no difference in performance between the 50% and 20% treatments.
A similar statistical result was returned for the foliage quality ratings. Nandina Cool Glow Lime achieved a passable aesthetic performance on Low water, but unlike the low-water performance expected of the straight species, the best aesthetic performance was achieved on High water in Region 2.
The Cool Glow Lime heavenly bamboo did not perform well from the start in Davis in our full sun trial. Only the high and moderate irrigation treatments put on a very small amount of growth over the season and no treatment approached an acceptable appearance at any time. All plants looked stressed and showed signs of sunburn and dieback. We are subsequently evaluating it in 50% shade for the 2022 irrigation treatment season. We do not recommend it for full sun in our region.
At South Coast REC, this cultivar attained a mean overall appearance rating of 3.0 based on scores early in the season, but by fall it was performing below an acceptable level with a few exceptions, even on the best treatment of 50%. There were significant differences in growth with only the moderate treatment achieving any positive growth while the low and high treatments saw significant loss in size. For these reasons, in this region we suggest this plant be placed where it will receive afternoon shade and, when using reclaimed water, irrigated at the moderate level.
