Meet the Proven Winners 2 gal. Red Perfecto Mundo Azalea Shrub. In a perfect world, azaleas would bloom for months instead of just weeks and have big, full flowers with pure and true colors. That's exactly what Perfecto Mundo azaleas do. Perfecto Mundo red azalea is a neat, rounded shrub that's covered with rich red blooms in spring, when other azaleas bloom, but then after a brief rest, begins blooming again in mid-summer and continues through frost. It's the perfect flower shrub for containers, landscapes, and as accents!
