Rhododendron 'Oxydol'(Exbury Hybrid)

Oxydol Exbury Azalea

Oxydol (Rhododendron ‘Oxydol’) is a deciduous azalea with white flowers. Its display arrives in the later part of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 2⅜ to 3⅛ inches across. Clusters commonly carry about 6-10 blossoms. Contrasting orange-yellow markings add detail within the flower faces.

The plant develops a narrow upright framework and a dense crown. The shrub sheds its leaves for winter, making its seasonal foliage and flower display especially noticeable. Cool-season foliage can develop bronze and red tones. Allow space for the branches to develop without crowding nearby plants or paths.

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.
