    Twice as nice as other azaleas!

    Why settle for just a week or two of flowers when you can enjoy up to five months of blooms? Large flowers appear in April, then rebloom in early July, continuing through fall until hard frost. Even high summer temperatures don't stop this enchantress from producing loads of late summer and fall flowers. The semi-evergreen foliage is disease resistant, and maintains excellent color year-round. Flowering lasts for 4-6 weeks in spring, and then another 12-16 weeks in summer and fall.

    Maintenance Notes: 

    For best rebloom, give Bloom-A-Thon azaleas a light, all-over trim when their spring bloom fades. This encourages new growth, which is what will be responsible for producing the flower buds for the rebloom.


    If you are growing Bloom-A-Thon azalea at the colder end of its hardiness range, avoid late season planting, which leaves the plant under-prepared for winter's challenges. Do not fertilize any Bloom-A-Thon azalea after mid-July. Like all azaleas and rhododendrons, Bloom-A-Thon reblooming azaleas benefit significantly from a 2-3" thick layer of shredded bark mulch.

    Fun Facts: 

    Bloom-A-Thon azaleas are semi-evergreen, which means they keep the foliage at the tips of their branches all year, dropping their inner leaves in winter.

    • I bought two of these, the one that I planted in full sun is about to die, and the one I planted in shade is thriving. It says it can grow in full sun, which is why I planted in a sunny spot, but I don't think that is actually the case, I think I will return it in another month if it's still not improving. The one that is thriving is absolutely beautiful.
