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 if not the most unique and cold hardy of the Encore Azalea selections, Autumn Sunburst produces an abundance of large and showy, 2.5-inch diameter blooms with coral to salmon pink centers that burst out to white ruffled edges in spring, summer, and fall against a backdrop of deep green, evergreen foliage. Butterflies love the flowers and blooming branches can be cut for use to create stunning indoor floral arrangements.
Landscape & Garden Uses
Growing to 3 feet tall and 3.5 feet wide, Autumn Sunburst Encore Azalea is a perfect choice for groupings, mass plantings, mid-size hedges or an accent in landscape borders and home foundation plantings. Its unusually attractive flowers make it a fine selection for growing in large 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 in woodland borders.
Suggested Spacing: 3 feet apart for solid hedge; 7 feet or more apart for space between plants
Note: For our customers who live and garden north of USDA Plant Hardiness Zone 6a, where this Encore Azalea variety is not winter hardy outdoors, you can enjoy it in containers that can be moved indoors during winter and placed back outside when temperatures warm up in spring.
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.
