    Flame Azalea is common to the Appalachians where it lights up the late spring woods with every pale and brilliant shade of yellow, orange, red, and salmon. The 2 inch, non-fragrant flowers are borne in open trusses just as their leaves are beginning to come out. Plants are loosely branched and upright growing to about 6 feet. Fall foliage color is yellow or pale red. It likes good soil that is well drained, and bright indirect light.
