Definition
Photo showing the two types of leaves. Note the smaller summer leaves at the top of the picture and the larger spring leaves below. The best definition of an evergreen azalea is the primary description of always having foliage to some degree.
Azaleas Are Rhododendrons
All azaleas are now placed in the genus Rhododendron, which are in the Ericaceae or heath family. This family dates back some seventy million years, allowing for a great deal of evolutionary diversity. Rhododendron is a large genus with over 800 species.
Plant Habit
Most evergreen azaleas are marketed commercially as shrubs, and this would be an apt description on original planting. In ten-years time though, depending on climatic conditions and the specific cultivar, a small shrub can grow considerably larger and in twenty or thirty years reach the size of a small tree.
Brief History
Historically, the first evergreen azaleas to enter the U.S. came from China and Japan via Europe in the 1830's as green house plants, the thought being that the plants were tender and required protection. By 1848 R. indicum varieties were being planted at Magnolia Plantation near Charleston, SC and were flourishing outdoors.
Flower Shapes and Sizes
Like their variety of plant sizes, evergreen azaleas also have multiple flower shapes and sizes. Flower size varies from the rather minute flower of R. serpyllifolium to the large-flowered Satsuki hybrids and Harris's 'Georgia Giant'. The most common flower form is the five-lobed single form.
Color
A primary reason for planting and cultivating evergreen azaleas resides in the colors that can be added to the landscape. In describing colors of evergreen azaleas, there are several general classifications. Those that are clearly of a single color are called selfs.
Leaves
Leaves are noted by their varying size and coloration with white varieties usually lighter in color and having less fall change before dropping than other more highly colored varieties. Leaves may be hairy, like R. oldhamii, or smooth and shiny as many of the Satsuki hybrids in character. Leaves of a few azaleas may curl or twist.

It’s difficult to think of a southern garden without envisioning azaleas graciously and vibrantly sweeping through the background. They are arguably one of the most popular ornamental shrubs in the South, along with our beloved hydrangeas. But azaleas aren’t just for Southerners to enjoy.
1. Azalea vs. Rhododendron: What's the difference?
Sometimes people get confused about the difference between an azalea and a rhododendron. That’s because an azalea is always a rhododendron, but a rhododendron is not necessarily an azalea. The confusion really lies with how they are named—specifically, their common names.
2. How to use azaleas in garden design
Azaleas are really a utility player in the garden. They provide both striking beauty when they are in bloom as well as a very reliable evergreen backdrop to help other plants shine throughout the year. Because of the many varieties available to choose from, you can probably find an azalea that meets almost any of your ornamental shrub design needs.

Azaleas are an extremely hardy shrub. In fact, I include them on my list of “bullet-proof plants” when talking to clients. But there are certainly things you can do to ensure a happier and healthier plant. Here are a few things to keep in mind from the get-go.
4. How to water, mulch, and fertilize azaleas
Once you have your azaleas in the ground make sure to give them what they need to thrive going forward.

If you’re looking to keep your azaleas their happiest … and you too (i.e., more flowers and less maintenance), it’s critical to understand when, why, and how to prune them.
6. Common Azalea Questions or Challenges

Introduction
Few plants can rival the spectacular floral displays of azaleas. Their vivid colors, profusion of flowers, and adaptability to a wide range of soils and climates make them one of the most popular flowering shrubs in Georgia. Although most people associate azaleas with spring, several bloom in summer and fall.
Grouping Azaleas by Characteristics
Azaleas are grouped into categories based on a number of plant characteristics, including whether they are evergreen or deciduous (shed their foliage in winter), and whether they are a native plant species or an introduced cultivar.
Planting Time
Azaleas can be planted successfully any time of year, provided they can be watered during establishment. Fall planting is best because it is less stressful to the plant than spring and summer planting. During the fall, temperatures are cooler and plants are going dormant.
Site Selection
Azaleas thrive in moist, well-drained soils high in organic matter. Filtered shade is best because some light is necessary for flower bud formation. An exposure providing morning sun and afternoon shade is ideal.
Planting Procedures
Before planting azaleas, always water them thoroughly. A dry root ball is difficult to re-wet once it is in the ground.
Propagation of Azaleas
Azaleas can be propagated from cuttings, seeds, or by a process called layering. Most evergreen azalea cultivars are propagated from cuttings to maintain their genetic purity.

How to Grow 'Stewartstonian' Azalea
'Stewartstonian' requires a moderate amount of maintenance. Locating it in part shade and in a soil that drains properly is a good start. But you also have to keep it irrigated, fertilized, and pruned.
Light
Plant this azalea in a part-shade location in the southern part of its range. In colder northern regions, it will do well in full sun.
Soil
Enrich the ground (and improve its drainage at the same time) by mixing in generous amounts of decomposed organic matter. These plants prefer acidic soil (pH 5.0 to 5.5), which may require amendment with sulfur, peat moss, or pine needles; or feeding with an acidifying fertilizer.
Water
Make sure the shrub's soil gets consistent moisture—a total of roughly 1 inch per week, preferably in at least two separate waterings. The roots on azaleas should never be allowed to dry out. You must keep the soil moist for this plant throughout the growing season, and applying mulch will help retain the soil moisture it needs.
Temperature and Humidity
'Stewartstonian' is well suited for the climate variations found in USDA zones 5 to 8. These plants don't grow well if subjected to prolonged temperatures over 90 degrees Fahrenheit, and may die out if winter temps fall below about minus-5 degrees. Azaleas typically don't react well to extremely dry environments.
Fertilizer
Fertilize this plant annually with compost. If necessary to lower soil pH, you can use an acidifying fertilizer.
