Deciduous azaleas drop their leaves in the fall, and grow a new set of leaves in the spring. There are 16 species of deciduous azaleas native to areas of the US, and more deciduous species are native to Japan. Thousands of hybrids have been derived from these species. Named hybrids are typically distinguished by their bloom color, type and time, and their foliage and plant habit—and by carefully keeping their labels intact.

Some deciduous azaleas are cold-hardy to Zone 3 (-40°F), while many more are cold-hardy to Zone 5 (-20°F) and warmer. R. austrinum, the "Florida flame azalea", is the most tolerant of warm temperatures, and is being bred into other deciduous hybrid azaleas (such as the Aromi hybrids below) to increase their heat tolerance.
