Azaleas typically bloom once a year in spring, with the bloom period lasting about two to three weeks depending on the weather and variety. Their bloom times generally range from February through May, varying by species, growing zone, and climate conditions

. However, some varieties, especially the Encore® Azaleas, are capable of blooming multiple times a year. These reblooming azaleas can flower in spring, summer, and fall, providing up to 4 to 6 months of floral display, and in some warm climates, even up to 8+ months of bloom

. The ability to rebloom depends on the azalea type and the climate zone, with warmer zones (USDA Zone 9 and above) favoring multiple bloom cycles

. In summary:

• Most azaleas bloom once annually in spring for about 2-3 weeks.
• Reblooming varieties like Encore® Azaleas can bloom 2-3 times per year (spring, summer, fall).
• Bloom timing and frequency depend on azalea variety, weather, moisture, and USDA hardiness zone
