(Deciduous Azalea, Milton Azalea, Rustica Azalea)
The enormous genus Rhododendron comprises more than a thousand species. They are naturally distributed on every continent except Antarctica, Africa and South America. The highest concentrations of species occur in the temperate and mountainous regions of China, Japan, Korea and Taiwan. Grown for their showy flowers, rhododendrons are garden favorites worldwide and have been highly hybridized. There are more than 28,000 registered cultivars.
Plants in this genus are extremely variable...
