Rhododendron canescensAlso known as:
Azalea candida, Azalea canescens, Rhododendron candidum
Mountain azalea is the most common and probably the showiest native southeastern azalea. It is a deciduous shrub with a delicate open form, growing up to 8'. The leaves are dark green and velvety hence the common name hoary azalea. It blooms in terminal clusters of trumpet-shaped, pink, lightly fragrant flowers with slightly ruffled petals. The stamens are unusually long and showy, curving upwards like false eyelashes. Flowers appear in spring, before new leaf growth has fully developed.
Rhododendron canescens can best be described as an elegant, shade garden show stopper. It prefers a sheltered location, and open filtered light. Rich, acidic, moist, well drained soil is best. Plants have shallow root systems and will benefit from a layer of mulch as protection during dry spells. Plants may be pruned to encourage a denser form and increased flower production. However, flowers appear on the previous year's growth, so any pruning should be done in spring after blooming. Bloom time will vary from March to May. Zones 6-8
Propagate by dividing mature plants, or by cuttings in summer. Can be propagated from seed. This is best achieved in a light, soilless medium and in sealed containers to retain consistent moisture until germination.
As with all rhododendrons, all parts of the plant are poisonous if ingested in large quantities. Individual reactions can be severe. This does however make certain species deer resistant.
