Rhododendron calendulaceum, the flame azalea,[3] is a species of Rhododendron. It is a deciduous shrub that grows up to 120–450 cm tall. This species of Rhododendron is native to the Appalachian Mountains in the eastern United States, ranging from southern Pennsylvania and Ohio to northern Georgia. It may be extirpated from Pennsylvania and Alabama.[4] It occurs naturally in mixed deciduous forests and is typically found in woodland slopes and mountain balds in the Appalachians,[5] where it prefers dry and rocky mountain woods.[6] The inflorescences of Rhododendron calendulaceum are visited by many animals such as bees, butterflies, hummingbirds and small mammals.[5] It is a popular cultivated plant due to its bright yellow, orange or red flowers.
