Bloom-a-Thon® Pink Double Rhododendron Shrub

Bloom-a-Thon® Pink Double Rhododendron is a welcome breakthrough that resulted with an azalea that first blooms in the early spring and then again in July, continuing to bloom until the first hard frost. This evergreen Proven Winners® selection is disease resistant and heat tolerant, making it ideal for climates that have not been conducive to raising azaleas in the past. With fully double blossoms, the flowers are thrilling pink and highly ruffled, putting on quite the show for at least 5 months. When the flowers are gone? You still have beautiful evergreen rhody foliage adding color to your late fall and winter landscape.
