Azalea is a popular flowering shrub from the Rhododendron genus, valued for its vibrant spring blooms and suitability for garden borders and shaded areas.
Fun fact Many modern azalea varieties, like Perfecto Mundo and Bloom-a-Thon, are bred to rebloom multiple times from spring through fall, extending their display beyond traditional seasonal flowering.[1][3]
