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 cultivar of Encore® Azalea was slightly hardier than the orange one and grew larger to an average width of 20” (50.9cm) and average height of 16” (40.8cm). Only one plant was lost on the lowest irrigation treatment, and there were no significant differences in average growth between treatments. As with the other cultivar, acceptable appearance was not achieved on the lowest irrigation treatment, and was incrementally better with each increase in irrigation (Table 18). As early as July, the lowest treatment performed significantly poorer than the highest treatment. Wilting, poor color, and tip browning became an issue on the two lowest treatments as the season progressed. Flowering during the pre-treatment winter months was not as abundant on the purple Autumn Royalty as it was on Autumn Embers. Plants did not rebloom by the October date that marked the end of our trial, but since a replacement species was not available until spring, this cultivar was left in the ground. A few of the plants that were left did rebloom later in the fall.
