Encore Autumn Sunset Azalea

Encore Autumn Sunset Azalea (Rhododendron 'Roblen')

Encore Autumn Sunset Azalea is a compact evergreen azalea valued for richly colored orange-red blooms and a dependable reblooming habit. It flowers heavily in spring, then repeats from late summer into fall to extend the season. Fine-textured, glossy foliage maintains a neat, rounded outline that stays attractive between bloom cycles. The manageable footprint suits foundations, paths, and mixed borders where steady color and structure are desired.

Distinctive Features

Vivid, sunset-toned flowers read bold in partial shade and create a strong focal splash against dark green leaves. A reliable fall encore sets it apart, delivering color when many shrubs are quiet. Dense branching and small leaves keep the plant tidy with minimal shaping. Subtle winter bronzing may appear in cooler climates, adding off-season interest.

Growing Conditions

• Sun Exposure: Partial sun to partial shade; morning sun with afternoon shade is ideal, or more sun with steady moisture to support rebloom.
• Soil: Moist, well drained, acidic soil enriched with organic matter.
• Water: Keep evenly moist, never waterlogged; avoid prolonged drought during bud development.
• USDA Hardiness Zones: 6 to 9.
• Mature Size: 3 to 4 ft tall and 3 to 4 ft wide.

Ideal Uses

• Focal Point: Repeat orange-red blooms create a standout seasonal display near entries and patios.
• Foundation Plantings: Compact evergreen form fits beneath windows and along walks.
• Mixed Borders: Threads spring and fall color among perennials and other shrubs.
• Low Hedges: Dense branching supports short, flowering borders with minimal shaping.
• Containers: Performs in sheltered pots with acidic media and consistent moisture.

Low Maintenance Care

• Watering: Water deeply and regularly during establishment and dry spells to support both bloom cycles.
• Pruning: Prune lightly just after the spring flush; avoid late summer pruning that removes the next set of buds.
• Fertilizing: Feed in early spring with an acid-forming, slow-release fertilizer; a light post-bloom feeding can support rebloom.
• Mulching: Maintain a 2 to 3 in layer of pine bark or needles to conserve moisture and cool roots.
• Notes: Protect from drying winter winds and maintain acidic pH; consistent moisture and light help encourage the fall flush.
