Autumn Royalty Encore Azalea offers vibrant year-round color to any garden. Autumn Royalty is a robust, upright variety with deep green foliage and large, rich purple blooms. Royalty was voted Azalea of the Year by the American Rhododendron Society. Unlike many traditional azaleas, Encore azaleas bloom best in full sun, so choose an area of your yard where they can receive at least 4-6 hours of sunlight. Autumn Royalty works well in foundation plantings or as a low growing hedge. Be sure to plant your Encore Azaleas in acidic to slightly acidic soil to maximize your bloom yield. Fertilize in the spring with a balanced fertilizer after the threat of the last frost has dissipated and feed once more in the summer to help you Encore bloom through fall. Encore Azalea is the world’s best-selling multi-season blooming azalea. In many areas of the country, Encore Azalea bloom during 3 seasons of the year-spring, summer, and fall. And, for areas of the country where azaleas don’t traditionally thrive, such as those in USDA hardiness Zone 6 and 7, you will see a spring or summer bloom, but not a fall bloom before your temperatures drop.
