Azaleas add color and bloom to the art of bonsai. When crafted with artistry and precision, an azalea bonsai flowers in clouds of pink, white and red. Azalea bonsai are most often shaped to resemble flowering trees. Azalea Bonsai may be grown either indoors or outdoors. If indoor, place in a well-lighted area with two or more hours of filtered sun. For best results move the indoor bonsai outside occasionally-but not during severely hot or cold weather.
