Rhododendron azalea 'RLH1-3P3'
PP21512 Plant propagation prohibited

Buy Bloom-A-Thon® White Azalea online. Is 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. The evergreen foliage is disease resistant, and maintains excellent color year-round. Flowering patterns can last 4-6 weeks in spring, with moderate to heavy blooms throughout the summer and fall months once they are established.
