Quick Summary

The flame azalea (Rhododendron calendulaceum) is a plant native to the eastern United States, known for its vibrant orange or yellow flowers. It is also referred to as the fiery azalea or yellow azalea.12

Azaleas, in general, are species of Rhododendron that are cultivated for their showy blossoms. While most rhododendrons are evergreen, azaleas are typically deciduous. Azalea flowers are funnel-shaped and often fragrant, differing from the more bell-shaped flowers of other rhododendrons. The flame azalea is one of several well-known North American azalea species, growing as a shrub between 1.5 to 6.5 feet tall.3
