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.

Uses Notes: 

Grouped or in mass plantings, mixed borders, containers, specimen plant. Good for foundation plantings or woodland gardens.

Maintenance Notes: 

Prefers light shade, adequate moisture, and fertile well-drained organic soil. Part sun to dappled shade is ideal and eliminates flower scorch in full summer sun. Prune to shape and fertilize after the first major spring bloom.

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.

  • 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!

    Outstanding My favorite plant, I recommend to others all the time and explain the reasons why I like it so much.
