Rhododendron Mandarin Lights

Northern Lights Hybird

Mandarin Lights (Rhododendron ‘Mandarin Lights’) is a deciduous azalea with orange 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 2¼ inches across. The flower tubes widen into flared faces that display the color clearly. Wavy petal edges give the clusters additional texture. The flowers are fragrant. Clusters commonly carry about 7-10 blossoms. Contrasting orange markings add detail within the flower faces.

The plant develops upright branching and a rounded outline. The shrub sheds its leaves for winter, making its seasonal foliage and flower display especially noticeable. 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.
