Rhododendron X bakeri Baker's Azalea, also known as Cumberland Azalea, is a compact and low-growing plant with horizontal branches. It produces striking orange to red flowers in a ball truss during the summer months but is not fragrant. The plant requires partial shade to high shade and rich, moist soil. It is hardy in zones 5b to 8b, but needs protection from the hot summer sun. Native to the eastern regions of the US, it may spread by stolons. The plant makes an excellent landscape plant in its own right and easily hybridizes with other species, producing beautiful hybrids in a broad range of colors. It has a relatively isolated natural range on the Cumberland Plateau in Kentucky south to Tennessee and the mountains of Georgia, Alabama, and North Carolina. Cumberland Azalea is most closely related to R. calendulaceum and can be distinguished from the latter by its flowering well after the leaves have expanded, eglandular pedicel and sepal margins, and usually abaxially conspicuously glaucous leaves.
