Carey, Jennifer H. 1994. Many nursery cultivars have been developed from flame azalea. Rhododendron fruits split along the sides soon after ripening and release many small seeds which are disseminated short distances by wind. Adequate humidity and soil moisture are required. Facultative Seral Species Flame azalea is intermediate in shade tolerance.
Flowers appear before or with the leaves and last several weeks.
Flame azalea is probably fire resistent because of its ability to sprout from the root crown. Fire may open up maturing forest canopies and rejuvenate declining flame azalea. Fire probably top-kills flame azalea. Flame azalea probably sprouts from the root crown when top-killed. Braun, E. L. 1950.
