Rhododendron chapmanii Chapman's Rhododendron, Chapman's Azalea1

Edward F. Gilman2

Introduction

Chapman's rhododendron is listed as one of Florida's rare and endangered plants. This shrub or small tree is also the only native evergreen rhododendron in the entire state of Florida. It grows to a height and width of 3 to 6 feet and has a relatively open and stiffly ascending branching habit. The tiny leaves of this plant are dark green in color and have an elliptic shape. The leaf undersides, petioles and twigs of this charming plant are covered with rust-colored scales. Pink flowers appear on the tips of the branches in the spring before the new shoot growth commences, and small brown capsules appear shortly after flowering ceases.

Use and Management

Chapman's rhododendron is lovely when planted singly or in mass beneath canopy trees. The plant can go largely unnoticed for 50 weeks of the year until it flowers.

Place this plant in an area of the landscape that receives partial to full shade. It will be most successful if located on a well-drained, acid soil. This species is cold hardy throughout Florida.

Chapman's rhododendron may be propagated by seeds or cuttings.

Pests and Diseases

Phytophthora root and stem rot can become a problem. Poorly drained soils, overwatering, and nutrient deficiencies will aid in the development of root rot.

This plant is also bothered by mites, mealy bugs, scale insects and various leaf and flower diseases. The best defense against these problems is to provide good growing conditions.
