Rosa ‘Zlepolone’ 

Rosa 'Zlepolone' Pretty Polly® Pink on moderate water in October 2021 at South Coast REC.

Summary

Pretty Polly Pink is a polyantha shrub rose that covers itself with prolific clusters of tiny pink cup-shaped blooms with easily accessible pollen for insect visitors. Bloom begins in April, increases through May and peaks in early June with significant flushes continuing through July and August. Occasional plants put on a significant flower show into September. Fortunately, even the faded blooms were a pleasant pastel pink or white until they shattered and fell from the plant. Because of its excellent performance on low water in Davis, it has earned the Blue Ribbon award. It displayed significantly more growth and better foliage and overall appearance scores on low water in Davis compared to the high water treatment. By October plants were beginning to look tired and some leaf edges were showing signs of drying, but this could be handled in a typical landscape situation by cutting plants back after late August flowering to allow new clean growth through fall. 

In Irvine, Pretty Polly Pink bloomed throughout the treatment period with huge flushes in June that yielded the highest possible overall appearance scores. Secondary flushes of bloom in August and September continued to keep the scores in the good to very good range throughout the season. Foliage was disease resistant and showed only the typical insect damage other roses in the trial displayed and began to fade by late September/ early October. Pretty Polly Pink displayed no differences in growth or quality ratings between treatments and we recommend it be irrigated on the low water level in this region.
