Since 1974, numerous species and cultivars of evergreen azaleas have been evaluated for hardiness and adaptability to south central Kansas (zone 6). Selections included Kurumes, Gable hybrids, Shammarello hybrids and others in various amended beds and in several landscape exposures. Hardiest cultivars include `Boudoir', `Caroline Gable', `Herbert', `Karens', `Pride's Pink', `Purple Splendor', and `Snowball' which flowered following -18F (-28C). Moderately hardy were `Elsie Lee', `Holland', `Girard Roberta' and `James Gable'. Best hardiness was found in cultivars and hybrids with Rhododendron kaempferi, and R. yedoense var. poukhanense parentage. Plants in soil amended with sphagnum peat moss or peat plus sulfur were superior to those in soil containing cotton burrs. Winter shade proved valuable in providing the best landscape site and northeast was generally better than a northwest exposure.
