Rhododendron Hello Dolly
Hello Dolly Rhododendron
Hello Dolly (Rhododendron ‘Hello Dolly’) is an evergreen rhododendron with pink and yellow flowers. Its display arrives in the early-to-middle part of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 2¾ 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 6 blossoms. Contrasting light green markings add detail within the flower faces.
The plant develops a rounded outline and a dense crown. A fine covering beneath the leaves adds detail to the foliage at close range. It can provide a flowering focal point within a mixed shrub border or woodland-edge planting.
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. Protect the foliage from strong afternoon sun.
