Summary

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.

This shrub rose was a good performer overall, with no significant differences in growth between treatments. There were blooms from April through October with the largest flush of flowers in April, followed by smaller flushes in June and August (Table 8). Pest and disease tolerance were good with some thrips damage showing late in summer followed by a late appearance of aphids that left the leaves shiny with honeydew. Foliage appearance generally declined starting in September. Best average annual quality rating in every category was achieved on 40% of ETo irrigation treatment.
