Rhododendron Polar Bear

Polar Bear (Rhododendron ‘Polar Bear’) is an evergreen rhododendron with white flowers. Its display arrives toward the end of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 4 inches across. The flower tubes widen into flared faces that display the color clearly. The flowers are fragrant. Clusters commonly carry about 8-10 blossoms.

Its foliage is retained through winter, keeping a leafy framework between flowering seasons. 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.
