About Autumn Sunset™ Encore® Azalea

The Autumn Sunset Encore Azalea is a reliable beauty that lives up to the Encore Azalea name! This selection features single-form, orange-red blooms with a splash of red flecks towards the center of the flower. These blooms are medium-sized, at about 2.5 inches across. Additionally, they’re quite prolific, and, like other Encore Azalea varieties, the Autumn Sunset is capable of reblooming up to 3 times a year!

The Autumn Sunset Encore Azalea isn’t all blooms though! This variety also features bright green evergreen foliage. Furthermore, its leaves are rounded, and glossy, with almost no leaf hair. This consistent foliage provides the perfect backdrop for its bright flowers to really shine.

The Autumn Sunset has a neat and compact dwarf growth habit that is quite easy to maintain with minimal pruning. At its mature size of 3′ H x 3.5′ W, it’s somewhat reminiscent of a muffin top. This is due to its naturally rounded growth habit.

Use this red-blooming azalea as a specimen, accent, informal hedge, or foundation planting. Otherwise, the Autumn Sunset is also great for containers or mass plantings.

Check out the Autumn Sunset’s sibling the Autumn Sunburst Encore Azalea, or take a look at a couple of other dwarf Encores, the Autumn Chiffon Encore Azalea and Autumn Fire Encore Azalea.

Autumn Sunset Encore Azalea Care

Hardy from USDA Zones 6a-10b, down to -10°F once well-established.

Plant the Autumn Sunset Encore Azalea where it will receive 4-6 hours of sunlight a day. If it receives too little sun, it will have reduced bloom and foliage production.

All Encore Azaleas require slightly acidic soil with good drainage to thrive. If you’re unsure of your soil pH, pick up a soil tester.

Water at least 2-3 times per week during the first growing season. In the second growing season, provide 1-2 deep waterings per week in average weather conditions. Afterward, provide supplementary water during times of extended drought and heat.

Fertilize 2-3 times each growing season with a slow-release or organic acidic plant fertilizer to promote growth and bloom potential. After the Autumn Sunset Encore Azalea has reached its mature size, it generally only needs one fertilizer application yearly.

How to Space Your Autumn Sunset Encore Azalea 

Space your Autumn Sunset Encore Azalea 2.5-3 feet apart for a seamless planting. Otherwise, plant them 3.5+ feet apart for gaps between plantings.

    Simply beautiful healthy plants. However, shipped too soon for planting. Will try to keep them as beautiful in their pots until middle of March.

    This is the 2nd time I have ordered from PLANTS BY MAIL and I love their plants. They come shipped very well and look so nice when they arrive. I am back to order some more and know I will have the same experience. I do recommend this company. You will not be disappointed. Dawn Shivers

    Phenomenal! Plants arrived quickly and are FAR SUPERIOR to those that were available locally. I’m overjoyed with the quality of the plants. Couldn’t be better.

    I purchased three of these last spring. They were beautiful but all three died over the winter. Company only warrantees that the plants arrive in good condition. After that, you’re on your own. I would not buy from this company again.

      We have a 30 day warrantee policy. After this it is incumbent upon the customer to provide care for their own plants. – Christy

    A bit more expensive than Lowe’s, but at least they had it in stock. Arrived alive and packed good.

    I can’t say enough good things about Plants by mail. We ordered 6 azaleas and they arrived in perfect condition and very promptly. I will be a customer for life. Thank you

  17. Wendy

    I purchased seven azaleas, and they are all full, lush, and beautiful! They arrived very quickly. UPS inadvertently kept some of my fist order, and PBM tracked them down and ensured that they arrived promptly, still in beautiful shape. Customer service was terrific!

    Thanks for the lovely new azaleas in my front garden!! I highly recommend them.

    We received 5 boxed azaleas that were in good condition with strong foliage, new growth and some flowers.
    We live on the shores of Lake Erie and are looking forward to having a splash
    of orange in the front of our house where we took down a large birch tree.
