Rhododendron

(Ericaceae - heath family)

Azalea, rhododendron. About 800 species of evergreen or deciduous shrubs and small trees. Native mostly to temperate areas of the Northern hemisphere, but found on all continents except Africa and S. America. Includes both the plants comonly known as rhododendrons and those known as azaleas. (While most rhododendrons have evergreen leaves and bell-shaped flowers, and most azaleas have deciduous leaves and funnel-shaped flowers, there is no real botanical distinction between the two.)

Rhododendrons generally require a well-drained acidic soil. A few species will tolerate poor drainage. Typically forest plants in their native habitat, most rhododendrons appreciate some protection from strong winds and intensely hot sun. It is desirable also to maintain a layeer of organic mulch over their root systems, to simulate the leaf litter of the forest floor.

Growing along streams and on moist, rocky wooded slopes, R. maximum tolerates the low pH associated with damp, shady almost bog-like conditions. Prefers partial shade moist, cool, acidic, well-drained, organic soil, tolerates and flowers in relatively dense shade. State flower of W. Virginia.
