Rhododendron austrinum


Rhododendron austrinum is known as the Florida Azalea and blooms in early spring before as the leaves are beginning to expand. The fragrant blosoms come in shades of orange through gold and yellow, and measure approximately 1 to 1.5 inches across. This species has very long stamens and the tube of the flower is often flushed with red but there is no blotch.

Discovered by Dr. A. W. Chapman before 1865, R. austrinum is similar in many respects to R. canescens including the sticky glanular hairs on the flower tube, but differs in the color variations which are orange to yellow rather than pink to white.

R. austrinum makes an excellent landscape plant as well as a valuable hybridizing resource, especially in southern gardens where heat tolerance is important.
