 azalea bloom times     early | middle | late | related pages
These charts show approximate bloom dates for a number of azaleas in central Georgia, USDA Zone 8. Azalea bloom times depend more on the weather than on day length. Thus, the actual bloom dates may vary a week or two either way depending upon the weather--a warm spring gives earlier blooms, while a cool spring gives later blooms. Similarly, they will bloom earlier in warmer zones, and later in cooler zones. Your bloom times will differ from the chart by about one week for every USDA zone.

Azaleas form flower buds during early summer if they receive adequate moisture. If they then have a period of four to eight weeks of temperatures below 50° F in the winter, they will break into bloom all at once the following spring, and stay in bloom about two weeks. Without the cold weather, they will bloom sporadically over a longer period. In USDA Zone 9 and warmer, many azaleas will bloom again in the fall.
