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.

Some time ago I tried to order 4 Ivory Encore azaleas and they were out of stock. I was impatient and foolishly tried ordering from a “big box” store. When they came 2 were torn loose in the box and many branches broken off, and the other two looked pale and sparse. We returned two and kept two. Then I got the notice that W.B. had them back in stock, so ordered the 4. Of course they were perfect and beautiful! I have all six planted and months later I can tell which are theirs because they are so much more full, green and healthy than the others!—————————————We are so glad you are pleased and we hope you enjoy your purchase for years to come! Thanks for the kind words and wonderful review! 🙂 Beth Steele | WBG
Azaleas were shipped quickly and safely. They were as described on the website. The price was reasonable and I appreciated the free shipping. When the azaleas arrived they were in packages with internal supports and the soil amply moist. The azaleas were healthy and are now thriving in my garden. Very pleased!————————————————————We are so glad you are pleased and we hope you enjoy them for years to come! Thanks for the kind words and great review! 🙂 Beth Steele | WBG
I purchased 2 Encore azalea bushes in June, & 2 months later, one made it and the other did not. Wilson Bros was very helpful and informative with my inquiry, and I could not be happier. They came packaged great in perfect condition, and Wilson followed up to ask about the plants, which was very useful as a beginning gardener who is trying to decorate her first home. Will be ordering from this company again!!

This azalea has a lovely soft white bloom which I like very much. It also has a smaller stature which is appropriate for where I want it. The plants arrived in wonderful condition. They were on sale and were in lovely condition, not the dried out wilted plants you often find on sale. I am very pleased with the plants.———————————————-We are so glad you are pleased and we hope you enjoy them for years to come! Thanks for the great review! 🙂 Beth Steele | WBG

Our first experience with Wilson Bros. Received plant quickly and in excellent condition—soil slightly moist and leaves/branches looking good. Planted next day and were rewarded with two blossoms the following week. Hoping for the best as it winters over here in zone 7a.————————————We are so glad you are pleased and we hope you enjoy it for years to come! Thanks for the great review! 🙂 Beth Steele | WBG
Ordered 7 One Gallon Encore Azaleas in different colors. They were packaged very well and arrived with no damage at all. These one gallon plants were nice and full, as good or better than you’d find at a local garden store and much better than any big box store. I very much like the one gallon version as the root ball is a modest size so planting them is not a major project, especially when you have hard native solid as I do.
Beautiful plants. Well packaged. Arrived healthy and transplanted very nicely.—————————————-Hi Michael, Thanks so much for taking the time to provide your review of the Autumn Angel Encore Azalea. We are so glad you are pleased and we hope you enjoy them for years to come! 🙂

I bought 7 of these Autumn Ivory azaleas from Wilson Bros Gardens and am very happy with them. I was having trouble finding them locally so tried Wilson Bros. They look very healthy and hopefully will do well where I put them. I like the foliage and needed something with a spring bloom. I will definitely use Wilson Bros again.———————————-WBG Reply: Hi JP, Thanks so much for taking the time to provide your review of the Autumn Ivory Encore Azalea.

I received my order of 15 azaleas yesterday. Even though the weather was in the high 90’s here, all the plants arrived in great shape. I’ll be planting them all this morning. Thank you.
