Azaleas fill open spaces with lush foliage and vibrant flowers in many different colors and shapes. While most types have an early summer or spring bloom, many shrubs produce blooms more than once a year. Fill your outdoor space with azaleas that bloom often and enjoy reblooming flowers from early spring to late summer.
Azaleas are a flowering shrub that is part of the rhododendron family. This bush thrives in almost any area in partial sun and comes in a wide variety of sizes, shapes, and colors.
There are deciduous and evergreen varieties of azaleas, and they produce vibrant blooms in varying shades of color. While often mistaken for rhododendrons, azaleas are generally smaller in size.
Unlike rhododendrons, azalea flowers usually have five stamens, rather than ten, and while there are some evergreen varieties, most are often deciduous. Fortunately, both types of shrubs come in a wide range of sizes and bloom colors.

Azaleas that Bloom More than Once a Year
If you love azalea and rhododendron shrubs, then repeat bloomers are perfect for your garden. Although they are not the most fragrant flowering bushes, many of the reblooming varieties bloom in spring, summer, and fall, and fill the outdoor space with flower colors ranging from white and pink to red and purple.
How Often do Azaleas Bloom?
Many azaleas flower only once per season, generally in March or April. The bloom time of these shrubs lasts up to two weeks. However, new cultivators, such as Encore azaleas, rebloom two or more times each year, providing the garden with flowers for several months.
Are there Different Types of Azaleas?
Generally, azaleas have single petal flowers and are limited in color, depending on the species. The deciduous type loses their leaves at the end of each season, while the colorful evergreen plants remain green all year round.
Traditional azaleas bloom once during spring, while newer varieties bloom two or three times a year. Some azaleas have a mature height of 3 feet while others reach a height of 8 feet. These shrubs come in a vast selection of colors, shapes, and sizes, and grow in almost any type of condition.
Where Should I Plant Azaleas?
The first step in deciding where to plant azaleas is to understand your USDA hardiness zone and compare it to the plants growing zone. Choose the right size shrub for your yard and place it in an area suitable for its mature height and width.
Avoid planting it in full shade or sun. Azaleas love receiving morning sun, light afternoon sun, or dappled sunlight throughout the day.
Are Azaleas Hard to Maintain?
Azaleas are a hardy shrub that requires very little maintenance to survive. These shrubs thrive in fertile and acidic soil, so you only need to fertilize your plants if you have low-quality dirt. Adding coffee grounds in azalea soil ups the acidity just enough and provides welcome nutrients for the shrubs.
Spread a layer of mulch beneath the shrub to retain moisture and encourage a healthy root system. Prune broken or dead branches as needed.
Luckily, azaleas are not a flowering bush with thorns so you don’t need to worry about getting stuck while trimming. Once established, azaleas need very little attention from you other than watering during dry periods.
