Rosa 'Radgor'

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 peach-colored shrub rose is smaller than most with dark green foliage. It displayed a somewhat inconsistent form halfway between shrub and spreader with a tendency to send out random sprawling canes and leave a low, open center to the shrub. There were no significant treatment-related effects on growth parameters or quality ratings (Table 15a). The plant showed excellent disease resistance and fairly good pest tolerance; the foliage showed slight edge burn on the lowest irrigation treatment and consistent midday wilt on all treatments.  Because of the inconsistent form combined with very little flowering after July, this plant on average reached just better than acceptable but not “very good” level of overall appearance rating after July’s second flush of bloom.

As evidenced by their ratings, participants felt this rose was acceptable at all three events with participants enjoying the “beautiful peach color flowers,” and they also found it attractive how the petal color faded to white as the flower ages. The ratings for this rose show how widely differently some individuals interpreted the floral display category (Table 15b). The scoring system for this category is intended to be quantitative, with participants determining what percentage of the plant is in flower. Due to the wide range of floral display scores, a few participants may have evaluated the floral display qualitatively, recording a score of how they felt about the flowers. This rose was also sold under the trade name Peachy Keen™.
