Summary

Oriental Pearl is a dense compact form of this species with deep green, ovate leaves typical of this shrub. White flowers appeared on some shrubs in April and May, but only a few bloomed heavily, which we think is more a reflection of the limited amount of time these long-lived perennials had been in the ground rather than the cultivar’s potential. When digging them up at the end of the trial, we also noticed that some specimens had severe root girdling from poor propagation methods at the nursery stage, and this certainly could also have affected their performance in this trial. Oriental Pearl in Davis outperformed plants in Irvine, where plants had acceptable appearance most of the year, but developed necrotic leaf tips and leaf loss as the season progressed. Plants had good to very good appearance in Davis on all treatments throughout the year. Since irrigation treatment had no significant effect on growth or appearance at either site, we recommend irrigation for Oriental Pearl at the low level in WUCOLS Regions 2 and 3.
