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.
Limoncello™ is a low-growing shrub or groundcover rose with simple, vivid yellow flowers borne in clusters. As they age, the flowers change from a pastel yellow to white before the petals shatter, giving the impression of multi-colored pastels most of the time. This rose was exceptionally good at self-cleaning. In Davis, the first full flush of bloom was in early May and it repeated again in July, though there were some blooms on the plants all the time (Table 15a). In Irvine’s cooler weather and often gray June and July days, the flowering on this rose did not reach the same levels as it did in Davis (Table 15c). It did bloom throughout the growing season in Irvine, if at lower levels than Davis. At both sites Limoncello™ was cut back to 1/3 its size in winter 2019.
Limoncello™ was popular with participants at the spring open house at UC Davis when it was in its first flush of bloom, earning it the number three spot on participants’ favorite plant lists (Table 15b). Although some insect damage was observed in Davis it didn’t much affect overall appearance, and it was virtually disease-free. Some minor powdery mildew was observed on plants in Irvine. These roses suffered some from the side effects of herbicide drift at our South Coast REC site. Roses are highly sensitive to herbicides, and the lower scores on this are due to these effects in some part. There was some leaf stunting and chlorosis, which we put down more to the herbicide than to any reclaimed water effect. There were no significant differences between treatments in growth (Figures 10b and 10d) or quality ratings at either site, with the exception of transitory vigor differences at South Coast REC. We recommend irrigating Limoncello™ on low water in WUCOLS zones 2 and 3.
