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.
Autumn Ivory Encore Azalea produces massive quantities of large, 2 inch diameter bright-white blooms in spring, summer, and fall that nearly cover the handsome green foliage. Attractive purple foliage provides interest during the cool season. University trials have shown Autumn Amethyst to be one of the most cold tolerant Encore Azalea varieties in the series. Butterflies love the flowers and cut blooming branches can be used to create stunning indoor floral arrangements.
Landscape & Garden Uses
Growing to 2.5 feet tall and 3 feet wide, Autumn Ivory is considered a dwarf Encore Azalea that is a perfect choice for groupings, mass plantings, mid-size hedges or an accent in landscape borders and home foundation plantings. It’s smaller size makes it a fine selection for growing in 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 along woodland borders.
Suggested Spacing: 2.5 feet apart for solid hedges; 5 feet or more apart for space between plants
Note: For our customers who live and garden north of USDA Plant Hardiness Zone 7a, 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.

I bought several Encore Azaleas from you in October. It was late in the season, no one else had Azaleas at that time and I was afraid they would not survive. But I had run over my previous Azaleas and needed to replace them before winter. I’m in the Pacific Northwest and was also concerned that the long trip would be bad for the plants. Well, they are thriving and are beautiful. I’ve attached a picture of one of them in their first season bloom with us.
Thank you for helping get these plants. My fear of long distance buying for plants is gone. Have a great spring and summer.——————————————————We are so glad you are pleased and we hope you enjoy them for years to come! Thanks so much for the awesome review and the kind words! 🙂 Beth Steele | WBG
