| 5’, upright to spreading. Flowers yellow, orange to scarlet, and shades in between, sometimes even differing slightly from branch to branch on the same plant.. Occasionally red, or partly salmon-pink blotched orange. William Bartram, the 18th-century plant explorer, in his book referred to this deciduous azalea as the "sky paint flower" of the Cherokees, so colorful are the blooms. Single, funnel-shaped ½-2 ½”, in trusses of 5-7. Blooms late mid to late season. Flowers open with or after the leaves. Leaf shape: broadly elliptic, elliptic-oblong, or oblong-ovate, both sides with fine short hairs, medium in size. Hardy to -25 F. Tetraploid; difficult to propagate from cuttings, but easily raised from seed. Native to the Appalachian Mountains from New York to northern Georgia. Grows best in areas of temperate summers—warm but not hot. Z. 5-7(8) | |||||
