Azaleas Azaleas are undoubtedly one of the most beautiful, prolific blooming plants available to grace your home. It is not unusual at all for an indoor azalea to be so covered with blooms that you have to look for the foliage. While they are close relatives to the rhododendrons and azaleas that bloom in your landscape, this type of azalea is not winter hardy in our area. All the hardy azaleas in our climate are deciduous, losing their leaves every winter.
Indoor azaleas are actually evergreen and grow prolifically in the deep South.
Azaleas will bloom for as long as a month at a time, especially if they are kept where it is cool. Like the lilacs, daffodils and crabapples that provide us with color each spring, azaleas have to go through a full season before they will bloom again. To trigger an azalea back into bloom, it should be kept outdoors throughout the summer. With luck, this cold treatment followed by warmer temps indoors will trick the plant into thinking it is spring again and it should bloom. If this sounds like too much trouble, simply thank the plant for the beauty it brought into your life and let it go.
