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 Lily Encore Azalea produces loads of very large, 3 inch diameter beautiful white blooms in spring, summer, and fall against a backdrop of deep green foliage on strong, upright plants. The flowers sometimes have occasional purple spots and stripes. Butterflies love the flowers and blooming branches can be cut for use to create stunning indoor floral arrangements.

Landscape & Garden Uses

Growing to 4-5 feet tall and 4 feet wide, Autumn Lily 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.

Suggested Spacing: 3-3.5 feet apart for solid hedge; 7 feet or more apart for space between plants

Note: For our customers who live and garden north of USDA Plant Hardiness Zone 6a, 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.

Unbelievable! A perfect transaction!
I look forward to receiving my third azalea!
Thanks.——————————————————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

Ordered 2 gallon but received 1 gallon size but Wilson Brothers made it right with no hassle. Disappointed with shipper. Boxes have arrows pointing up but all of these were laying on their side and one box must’ve been upside down for part of the trip based on the location of the plant inside the box. Plants seem hardy despite broken leave and limbs. I planted them and think they will be okay. There’s no need for the shipper whether UPS or FedEx to treat these boxes which clearly contain plants, with arrows pointing up , with such disregard.———————————————So sorry about the shipping, we try so hard. We are so glad you are pleased and we hope you enjoy it for years to come! Thanks for the kind words and great review! 🙂 Beth Steele | WBG
