This entry has yet to be reviewed and approved by L2G editors.
The cool-hued and more cold-hardy Autumn Lilac™ azalea, also known as Rhododendron ‘Robles’, is part of the Encore Series. It is a small rounded shrub with purplish lavender-pink flowers with tiny speckles. These appear in profusion in the spring and then again for a lighter encore in the fall. The Encore Series is a collection of hybrids developed by Robert E. "Buddy" Lee of Independence, Louisiana. They are all hybrids of parents from Kurume and Southern Indica azalea lines.
This rounded evergreen shrub is compact and best-suited to warm, temperate climates. Its leaves are dark green, elliptical to oval and slightly hairy. The single-form flowers are tubular, funnel-shaped and pale pink with dark pink speckles and ruffled edges. Encore azaleas produce full floral displays but rarely become blanketed in blooms the way Kurume hybrids or Southern Indica azaleas do.
Encore azaleas are shallow-rooted and grow best when planted in organic-rich, moist soils with good drainage. Establishment is better if heavy clay and sandy soils are amended with organic matter. Acid soils are best for good plant growth and performance. Mulch well over the root zone to conserve moisture, suppress weeds, and moderate temperature extremes. Azaleas grown in partial sun to partial shade perform better. Those grown in partial sun should be shaded from hot midday and afternoon sun, though Encore azaleas will tolerate more sun than most. Lightly prune in spring as needed.
Use this twice-blooming flowering shrub as an accent in garden beds and borders, or in foundation plantings. Autumn Lilac™ even does well in large containers.
