Rhododendron

Dorothy Rees Evergreen Azalea

Dorothy Rees (Rhododendron ‘Dorothy Rees’) is an evergreen azalea with white flowers. Its display arrives near the middle of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 3¼ inches across. The flower tubes widen into flared faces that display the color clearly. Wavy petal edges give the clusters additional texture.

The plant develops a rounded outline. The green leaves have a glossy surface that gives the foliage a distinct presence between flowering seasons. Its low early growth makes it useful near the front of a planting where the flowers remain easy to see.

Give it acidic, humus-rich soil that stays moist and drains freely. A sheltered position with filtered light or morning sun is a useful starting point; protect the roots from prolonged drying and keep mulch clear of the stems.
