Name and classification

About the name
Older horticultural writing sometimes called this plant Indian azalea or Azalea indica, and used the name now given to the separate Satsuki azalea (Rhododendron indicum). Many potted come from crosses between species, so flower color alone cannot tie them to this wild species.
