About Autumn Starburst™ Encore® Azalea

he new Autumn Starburst Encore Azalea is an azalea you won’t regret planting! The Encore Starburst produces bicolor coral pink blossoms with bold white margins. These gorgeous flowers emerge in the greatest numbers during a massive initial spring bloom. Afterward, they will produce 2-3 more slightly smaller reblooms before the onset of winter. With warmer zones having the potential to see even more bloom cycles!

The Autumn Starburst Encore Azalea produces glossy and rounded oval leaves. This bright green foliage remains evergreen all year long. Therefore, your landscape will never be bare with this azalea!

Use this pink and white blooming azalea in your landscape or garden as a specimen, accent, low hedge or foundation. Furthermore, it shines in container plantings, whether as a mixed container or a standalone.

With a mature size of 3 feet H x 3.5 feet W, this azalea is perfect for low-maintenance gardeners.

Autumn Starburst Encore Azalea Care

Hardy from USDA Zones 6a-10b. Provide some winter protection for the Autumn Starburst during its first couple of growing seasons to help ensure survival.

Provide 4-6 hours of direct sun daily to ensure maximum blooms. Filtered sun all day can work, however, be sure that enough light is coming through. If not, you will not have as many blooms.

Plant the Autumn Starburst Encore Azalea in well-draining acidic soil for best results. Azaleas are prone to root rot, so be sure that your soil has good drainage to ensure long-term success.

Water regularly for the first growing season. 2-3 waterings per week is generally sufficient, with increased frequency needed in times of high heat and drought. During this establishment period, check regularly to ensure that your plants are neither drying out or staying soggy.

Fertilize with an acidic plant fertilizer in spring once the threat of frost has passed. Moreover, regular fertilizer applications will help to encourage increased blooming and growth.

Autumn Starburst Encore Azalea Spacing Recommendations

For seamless foliage, plant your Autumn Starburst Encore Azaleas 2.5 feet apart. Otherwise, plant them over 3.5 feet apart for space between plants.

    It is so pretty you would think it is not real

  2. Gale V (verified owner)

    This Azalea arrived in mint condition. It even had blooms on it! (This is in Virginia in the month of October) If you are on the fence about receiving plants/shrubs in the mail, don’t be with this company.

  3. Robert Crocker (verified owner)

    Plants in very good condition. Chose Plants by Mail because they were relatively close-in east TN arrive in 2 days. Would like to minimize time in the box–don’t think the plants like that.
    Also a lot cheaper than another mail order place similar distance away.
    Think the plants were in better shape too.

  4. Nancy L Tonetti (verified owner)

    Plants arrived in excellent condition and looking healthy. I’m glad to be able to choose plants that I can’t find locally.

  5. Scott Buchanan (verified owner)

    Two Autumn Starburst plants received in perfect condition. We can’t wait for them to bloom.

  6. Terry Johnson (verified owner)

    They came in one piece looking good.

  7. Terry Johnson (verified owner)

    They came quickly and in one piece

  8. Cameron Holt (verified owner)

    I always feel it’s a risk to get plants shipped to you, but all my orders from plants by mail have arrived just like I picked them out at my local nursery

  9. Bryan Houser (verified owner)

    Plants arrived in top notch shape and very full. Plants were packaged excellent and arrived quickly. Just waiting for the first bloom.

  10. Cheryll Rogers (verified owner)

    These plants arrived quickly after placing the order. The package was wrapped carefully, and the plants looked great when I opened them – very healthy. I planted these immediately, and so far so good. I’m hoping for continued success!

  11. psalms_91_1 (verified owner)

    We purchased 4 of these and they arrived in wonderful condition. One of them had beautiful blooms on it! Awesome! Can’t wait to see them all blooming…anticipation!

  12. lincv11 (verified owner)

    Plants arrived in excellent condition and look beautiful

  13. Carl Berndt (verified owner)

    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.

  14. Joan Musumeci (verified owner)

    Was very happy with the Autumn Starburst™ Encore® Azaleas I purchased. The only reason for the 4 stars instead of 5 was the shipping.. My order arrived in two shipments several days apart. The first box was crushed (delivery service problem). Luckily there was not much damage to the actual plants. The second box arrived about a week later. I actually emailed them because I thought the shipment was lost. That plant arrived fine.

  15. Deirdre Haynes (verified owner)

    I have been dreaming of adding azaleas to my garden but feared it would always be a dream. Autumn starburst has bloomed 3 times since i put them in a few months ago. They are happy and thriving with full west exposure sun in my sw florida zone 10a border 9b garden. The heat and humidity dont seem to be the slightest issue for this series. They are doing so well i just added 3 autumn twists in my new bed.

  16. Charlotte M. (verified owner)

    Came in perfect condition. Healthy. This is my 3rd time to purchase my bushes from this website. Never disappointed.

  17. kaybuckles (verified owner)

    Plants arrived in excellent condition. Great specimen, full of blooms.

  18. Ashdale Pierre (verified owner)

    Arrived in great shape. Took a beating this year because a tree branch fell on it and STILL bloomed wonderfully and is recovering quite quickly. Love love love the blooms and love that I ordered it from PBM.
