Description
In 1998, the release of the first reblooming Encore Azalea changed the Azalea world forever. Since then, over 30 Encore varieties have been released. When provided enough sunlight (6 or more hours per day) all varieties bloom in spring and then repeat summer into fall.
One of the new introductions to the Encore Azalea family, Autumn Starburst features an abundance of dazzling bicolor white flowers with a coral-pink stripe bursting from the center and down the middle of each petal. The 2.5 to 3 inch diameter flowers stand out remarkably well against the 3 feet tall by 3.5 feet wide mound of deep green evergreen foliage. Butterflies love the flowers, and blooming branches serve very well for cutting to create stunning indoor floral arrangements.
Landscape & Garden Uses
Growing in a rounded mound to 3 feet tall and 3.5 feet wide, the Autumn Starburst Encore Azalea is ideal for is in groupings, mass plantings, low hedges or an accent in landscape borders and home foundation plantings. It is also a fine selection for growing in containers and pots, which can be strategically placed to dress up decks, patios, porches, and other outdoor living spaces. Because they like sun to part shade, Encores do quite well under tall trees and along woodland borders. A fine addition to azalea and rhododendron gardens, sunny woodland borders, and cottage gardens.
Suggested Spacing: 3 feet apart for solid hedges; 6 feet or more apart for space between plants
Growing Preferences
We’ve been growing Encore Azaleas in our gardens since they were first released in the 1990’s and can say with confidence that when planted right, and in the right spot, Encore Azaleas are among the easiest azaleas easy to grow.
Soil: When planted in the ground, Encore Azaleas adapt well to most soil types. In general, like all other azaleas, the Encores prefer an organically rich, moist but well-drained acidic soil. Constantly soggy or wet soil is problematic for azaleas. Heavy clay, quick-draining sand, or otherwise poor soils are best amended with organic matter or other soil amendments to provide sufficient nutrients, better soil drainage, and/or moisture retention.
In containers, a 50/50 blend of professional potting mix and potting soil is suggested. Make sure the pot has a hole(s) in the bottom that allow for sufficient drainage. As mentioned above, Encore Azaleas do not like a constantly soggy soil.
Sun: Encore Azaleas will grow in sun or part shade. For best flowering and reblooming, we recommend at least 4 hours or more of direct sunlight per day. All-day lightly filtered sun, such as under tall trees, is okay. In regions that experience very hot summers with intense sunlight, Encore Azaleas might appreciate a break from direct sun during the mid afternoon hours.

Our 6-pack arrived promptly and in great shape. We couldn’t wait to see them and they were all beautiful. We could not plant them for 3 days because we had out of state company, so we placed them in a partial shade area together and watered them very day. We prepared our soil as recommended. They have now been in the ground and thriving for over a week. Very happy with the plants, the price and the FREE shipping!—————————————–We are so glad you are pleased and we hope you enjoy them for years to come!
