Rhododendron Purple Passion

Purple Passion Rhododendron

Purple Passion (Rhododendron ‘Purple Passion’) is an evergreen rhododendron with purple flowers. Its display arrives near the middle of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 3 inches across. The flower tubes widen into flared faces that display the color clearly. Wavy petal edges give the clusters additional texture. Clusters commonly carry about 12-16 blossoms. Contrasting reddish purple markings add detail within the flower faces.

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.
