A parade of color: the magic of native azaleas

Spring fever always spikes for me when the first native azaleas begin blooming, brightening woodlands and landscapes with fragrance and color. Yet these spectacular native plants, with their wide range of colors and bloom times, are seldom seen in local gardens.

While azaleas have long been a popular shrub choice in the South, the familiar, evergreen azalea species came from Asia and fail to adequately support our local wildlife. Native azaleas, on the other hand, offer superior environmental adaptability and improved pollinator support, as well as being low maintenance and incredibly beautiful. 

Currently taxonomists have identified 17 species of American azaleas, and Georgia is lucky to claim at least 12 as native, more than any other state! These vary in color, bloom time and fragrance, offering wide appeal. The first species to bloom is the Piedmont azalea (Rhododendron canescens) with its beautiful, pink-laced, fragrant white blossoms. 

True gems of the Southeast, native azaleas are deciduous, meaning they drop their leaves in winter, but their buds develop during this time — offering a glimpse at the beauty ahead. The earliest species bloom before leaves emerge, putting on an especially pretty show. In autumn, leaves often turn vibrant colors, providing ongoing interest. With careful planning and species selection, one can have native azaleas blooming from March into September in Georgia.

Native azaleas have a more airy, freeform shape than their Asian cousins. They are also hardy, non-aggressive and well-adapted to our climate. After all, these azaleas have been growing wild as understory plants for thousands, if not millions, of years!

Consider adding these lovely plants to your landscape as borders, backgrounds or specimen plants. Here are some guidelines and features:

— Fragrant flowers often open before leaves and continue as leaves appear

— These slow growers can get as large as 8 feet wide and 15 feet tall

— Morning sun with afternoon shade is ideal, but the shrubs can often adapt

— Azaleas prefer acidic soil, pH range of 4.5-6.0. (Test soil through your local UGA Extension office to determine pH before planting)

— Fall is always the best time to plant, though any time will work with attention to site and hydration during establishment 

— Though rarely needed, avoid pruning after July 1

Among the likeliest native azaleas to find locally, in order of bloom time, are:

— Piedmont (R. canescens) white with pink
— Oconee (R. flammeum) yellowish-orange, orange, red
— Florida Flame (R. austrinum) yellow, reddish tube
— Red Hills (R. colemanii) white, pale pink, pale yellow
— Flame (R. calendulaceum) yellow to orange to deep red.
— Swamp (R. viscosum) fragrant white blooms
— Plumleaf (R. prunifolium) orange to vivid red
— Smooth, Sweet (R. arborescens) fragrant white blooms

You can see the season’s earliest bloomers, R. canescens and R. flammeum, now! Visit the native plant garden beside the Museum of Arts and Sciences in Macon. This Bibb master gardener-maintained shade garden is located off the parking lot near the planetarium.
