Delaware Valley Azalea is a classic evergreen azalea known for its abundant, pure white spring blooms and clean, refined appearance in the landscape. It thrives in USDA Hardiness Zones 6-9 and reaches a mature height of 5-6 ft. tall with a dense, upright habit that makes it well suited for foundation plantings, borders, and informal hedges. For best results, plant in partial shade with well-draining, acidic soil, water consistently during establishment, and apply mulch to maintain soil moisture and protect shallow roots.
