Cerastium tomentosum in May 2013. Photo: SK Reid. Snow-in-summer did not turn out to be as hardy a plant as we had hoped. The average overall appearance of these plants was barely acceptable at all irrigation levels during the second year.
Ceratostigma plumbaginoides in full sun in June on 60% ET0. Photo: SK Reid. Since we grew this species in both the full sun and shade, both treatments results will be discussed together for comparison.
Delosperma cooperi in May 2013 on 20% ETo. Photo: SK Reid. As a flowering groundcover, this iceplant was fairly fast spreading and sturdy in the trials field. It showed some sensitivity to hard frost, turning purple and dying back in some cases.
Isomeris arborea in May 2013 on 20% ET0. Photo: SK Reid. This southern California native species was extremely difficult to analyze due to 50% mortality rates on the 80, 60, and 20% treatments, leaving only three plants on each of these irrigation levels.
Rosa 'Meisentmil' Lemon Drift in May 2018 before treatment effects. Photo: SK Reid. Lemon Drift is a prolifically blooming groundcover rose that performed at a very good level on all irrigation treatments with no significant differences in overall appearance between treatments (Table 16a).
Rosa 'Meikokan' Tequila Supreme in full bloom in May 2018 before treatments. Photo: SK Reid. The color of the blooms on this vigorous and dense shrub rose is unique and eye-catching, and the ruffled petals just add to the appeal. Open House participants mostly commented on this aspect of the plants.
Lomandra longifolia 'LM300' Breeze on 20% of ETo in September 2018. Photo: SK Reid. After previously evaluating this plant in the full-sun field, where we noted uneven performance, trials staff were interested to see if the plant would perform better in this region when grown under 50% shade.
Abelia grandiflora Wevol Bella Donna in April 2018 before treatments began. Photo: SK Reid. Overall, we feel this cultivar of Abelia never reached its full potential in our trials, though several individuals did reach acceptable overall appearance ratings.
Illicium parviflorum PIIIP-I BananAppeal in April 2018. Plants already showing incompatibility with our soil or climate conditions. Photo: SK Reid. Trials staff were excited to learn a new genus and family when we received a request to evaluate this cultivar.
Rosa Harlow Carr at first bloom in April 2016. (Before treatments began; 20% ET0.) Photo: SK Reid. This is a fragrant, pink David Austin shrub rose. Like so many English roses, it attained greater height and width in our region than advertised by the breeder.
