Delaware Valley White Azalea (Rhododendron 'Delaware Valley White') is a lovely addition to any landscape. For one, white flowers are uncommon but serve as fine complements to flowers and foliage of all colors. Delaware Valley White produces pretty azalea white flowers about 2 to 4 inches in size each spring. They rise above evergreen foliage. For a showstopper, year-round hedge, plant several of the shrubs along a garden border, sidewalk, driveway or before low structures.
Growing to about 3 or 4 feet tall and wide, Delaware Valley White Azalea is a perfect low hedge or border. It also can stand out in the center of a garden bed or against a fence or house. Butterflies are drawn to the big white flower clusters and the lush green foliage shines in the garden through winter. Each flower has about 10 long stamens, adding to the delicate beauty of the white blooms. The shrub should thrive in part sun in zones 5 through 8.
Delaware Valley White Azalea Care
Azaleas like fertile, well-draining soil that is acidic (about 5.5 to 6.2 pH). Although touted as a shade-loving shrub, Delaware Valley White Azalea needs some sunlight to flower well. So, morning sun or dappled shade from a tree work best. The shrub needs consistent, nearly constant moisture. Add a layer of organic mulch (such as bark or pine needles) around the plant to keep moisture from evaporating. Prune your azalea in late spring after it is done flowering.
Delaware Valley White Azalea Spacing
For a gorgeous white and green hedge, place your group of Delaware Valley White Azalea nearly 3 feet apart to account for future size.
