Azaleas are handsome shrubs with large clusters of pink, red, orange, yellow, purple, or white flowers. The better-known native American azaleas, often cultivated, include the flame azalea (R. calendulacea) of the Appalachians; the pinxter flower (R. nudiflora) and the fragrant white azalea, or swamp honeysuckle (R. viscosa), of the E United States; and the Western azalea (R. occidentalis) of California and Oregon. Most azaleas grow in damp, acid soils of hills or mountains. The rose-purple R. canadense, a rare species with an unusually northerly range (from Pennsylvania to Newfoundland) is the rhodora immortalized by Emerson. Many of the brilliantly flowered garden varieties are native to China and Japan, where the genus is most abundantly represented. The popular Ghent azaleas are hybrids. Dwarf azaleas are grown by florists as pot plants. Azaleas are classified in the division MagnoliophytaMagnoliophyta
