Description

If you're looking for a show-stopping reblooming azalea, check out Perfecto Mundo® Double Purple! 

The Bloom-A-Thon® series is twice as nice as (and more shade tolerant than) other azaleas!

Why settle for just a week or two of flowers when you can enjoy up to five months of blooms? Vivid purple flowers cover this attractive, mounded plant in spring. After bloom, the plant takes a brief rest, then comes roaring back with more red flowers through frost. Even high summer temperatures don't stop this beauty from producing loads of late summer and fall flowers. The evergreen foliage is disease resistant, and maintains excellent color year-round.
