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 Angel Encore Azalea produces an abundance of large and beautiful pure-white blooms in spring, summer, and fall against a backdrop of glossy, deep green evergreen foliage. Butterflies love the flowers and blooming branches are great for cutting and use to create stunning indoor floral arrangements.
Landscape & Garden Uses
Growing to 3 feet tall and 3 feet wide, Autumn Angel Encore Azalea is a perfect choice for groupings, mass plantings, low hedges or an accent in landscape borders and home foundation plantings. It is also 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 in woodland borders. Butterflies love the flowers, and blooming branches serve very well for cutting to create stunning indoor floral arrangements.
Suggested Spacing: 2.5 feet apart for solid hedges and mass plantings, 6 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.

Arrived in excellent condition. Planted, following advice given on your website. Plant is doing well and didn’t even shock. Only reason this isn’t a 5 star is because the plant is a bit “leggy”, not as well formed as the other two purchased at the same time.——————————–Thanks so much for your review. Let us know if there’s ever anything we can help you with. 🙂 – Beth | WBG
I received my six encore azaleas and they are so healthy. I’m looking forward to the beautiful blooms that I will have each year. I recommend your company to everyone for I have ordered the last two years from you and my plants are wonderful.——————————————We are so glad you are pleased with your purchase!

My azalea arrived with another plant I ordered in chilly March. When I opened up the extremely secure packaging, my azalea was pert and bursting with lovely, evergreen foliage. In the short time I have had it, it is doing well in my garden which is having daytime temps in the 40’s and 50’s and night time temps in the upper 30’s. I have so many deciduous plants that even small. it is filling in a much needed green spot in my garden. It will look beautiful with its white blooms and green foliage next to my new blue mist fothergilla and Arctic Sun Dogwood behind it. Then after its first bloom it will bloom again in the fall when the fall colors arrive along with blue purple asters and September Charm anemones. I am more than delighted to have found Wilson Bros, very impressed.—————————————-Thanks for the kind words! We are so glad you are pleased with your purchase! Thanks for the great review!

My Angel Encore plants arrived in perfect condition. Everything was well secured and as fresh as they left the nursery. I can hardly wait for them to bloom, hopefully next spring.———————————————————————————-Thanks so much for the great review! We are so glad you are pleased! And they may bloom in the Fall! 🙂 Beth Steele | WBG
This is a beautiful azalea with its pristine white flowers and glossy green leaves. An added bonus is that it is an “Encore” variety and a repeat bloomer. It is the perfect size when you want an azalea that does not get too large.———————So glad you are pleased! Beth | WBG

side yard – easy peazy and it is thriving! I will be back
