Rhododendron schlippenbachii

Royal Azalea

Royal azalea (Rhododendron schlippenbachii) carries broad pink flowers in spring and colorful leaves in autumn. This deciduous shrub develops an upright, rounded framework that is especially effective in a sheltered woodland garden.

The plant develops a rounded outline. The leaves are shed for winter.

Choose a position with partial shade. Provide acidic, humus-rich, well-drained soil and maintain even moisture. Prune after flowering if adjustment is needed.
