    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 beauty from producing loads of late summer and fall flowers. 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 that they keep the leaves at the ends of their branches but lose nearly all of their inner leaves.

    • Blooms Spring, Summer and Fall. That's what they claim. Bloomed about for 3 week after purchase in early Spring...No frost. And that was it. They also don't respond to feedback/email, unless you let them know how great they are.

    • Top performer this spring! I planted it last fall. It receives 3-4 hours of morning sun and dappled shade the rest of the day! It is covered in blooms right now. Zone 7a

    • I bought three of these in spring of 2012, planting them in mostly shade as directed. They performed EXACTLY as advertised! They survived a BRUTAL summer of heat and drought (I use above ground drip system). They were blooming when I planted them, they bloomed again from mid-July until frost - which was late - sometime in November. Their blooms this spring outlasted my other Azaleas. I bought three more yesterday to plant in the same bed! I HIGHLY recommend them!
