Rhododendron cumberlandense - Cumberland Azalea
Often confused with Flame Azalea but it is a redder side of orange and blooms later. It prefers direct sunlight and requires water in heat. Does not propagate easily from cutting; if pruned too hard, it may die. If you collect your own seeds in November and December from the dried pods and sow in December to February, seedlings will flower the second year if they grow well.
Semi-Shade, Woodsy Soil, Early/Late Spring, 3-4' Tall, Zones 5-8
