Rhodoendron Flame Azalea

Flame Azalea Shrub - Rhododendron calendulaceum

The flame azalea shrub stands upright and features big, beautiful vase-shaped flowers. Measuring between six feet to 12 feet tall and wide, this shrub has bright green foliage and yellow, orange and red flowers that grow in large clusters. The non-fragrant flowers bloom right before or at the same time as the leaves, which will fade to a yellow or red color in the autumn. This deciduous, ornamental shrub grows natively in the low areas of the southern Appalachians, blooming in late spring. It is one of 16 species that are native to America, Japan, and China. Many other related varieties have been cultivated.

The slow-growing flame azalea thrives best in the acid, dry, and rocky soil. As a perennial, this shrub enjoys moist, well-drained soil in partial shade. It is one of the few plants that prefer shade to sun and thrives in such conditions. New plants require careful pruning to look their best as well as reduce disease issues and pest problems in the long run. The flame azalea does well in hardiness zones six to nine.
