Overview
Autumn Sunburst Encore Azalea brings coral-pink flowers with white ruffled margins to evergreen beds. This reblooming hybrid produces a spring display and repeat flushes in summer and fall. It is not Florida native.
Mature Size and Habit
Plan for 3 feet tall and 3.5 feet wide. Its compact and rounded habit needs room to develop without frequent shearing. 
Best Landscape Uses
Use in layered borders, foundation beds, or grouped accents. Allow its full spread beside paths and windows. Use acidic container mix where soil is alkaline.
Sunlight
Provide four to six hours of direct light, preferably morning sun with afternoon shade. Avoid reflected afternoon heat. Dense shade reduces rebloom.
Soil, Drainage, and Irrigation
Use acidic, well-drained soil and test pH before planting. Keep the root crown above settled grade. Water the root ball during establishment, then deeply during dry periods. Avoid soggy soil and mulch against stems.
Best Planting Season for Tampa and Central Florida
Fall through early spring reduces heat stress during rooting. Year-round installation requires dependable establishment watering. Delay planting during a freeze, severe drought, or saturated conditions.
Pruning and Maintenance
Prune lightly after spring flowering. Remove dead or crossing stems instead of clipping into tight cubes. Monitor lace bugs and yellow foliage. Diagnose drainage and soil pH before adding fertilizer.
Wildlife Value
Flowers attract visiting pollinators, while branching provides small-scale shelter. Include native host plants elsewhere for wider wildlife support.
Cold and Heat Sensitivity
The listed hardiness range is USDA zones 6a–10b. Cold injury is less limiting than hot, dry roots in Tampa. Protect new plants from extreme exposure and avoid saline irrigation.
Safety, Roots, and Placement Warnings
Azaleas contain grayanotoxins and are toxic if eaten by people or pets. Keep clippings away from animals. They lack prominent thorns. Shallow roots need protection from digging and repeated foot traffic.
Invasive Concerns
This cultivated hybrid is not a native azalea. Use it in managed landscape beds, not habitat restoration. Remove unwanted seedlings and never discard nursery material in natural areas.
