Probably the most widely cultivated of our Azaleas, these native shrubs have flowers an inch or more across of varying shades of orange or yellow and add brilliant splashes of color to the spring forests. Another native Appalachian species, these plants grow in the deciduous forests and on forest margins in our mountains. May - June [Justice, William S. and Bell, C.

Since the time of William Bartram this spectacular plant, "the most gay and brilliant flowering shrub yet known", has been a great favorite. It grows at the lowest altitudes up to 5,800 feet, especially in fairly dry open forests where pines and oaks predominate. Ordinarily the flowering period begins in late April at the lower elevations and progresses upward until late June, when the plants in the higher mountains come into full bloom. The flowers range from pale yellow to a striking rich orange, since flame azalea hybridizes readily with other species. While many specimens grow 5 - 8 feet tall, some attain a height of 18 feet in the Great Smokies. [Stupka, Arthur, Wildflowers in Color.
