AZALEA DELAWARE VALLEY WHITE
‘Delaware Valley White’ is an evergreen azalea which grows to 3-4’ tall over the first 10 years. Tubular, funnel-shaped, usually single, white flowers (to 2.5” across) bloom in clusters in early mid-season (late April-May). Obovate to oblong green leaves usually turn yellow over winter. Some authorities list this cultivar as a Glenn Dale hybrid.
AZALEA CARE: Best grown in acidic, humusy, organically rich, medium moisture, moisture-retentive but well-drained soils in part shade. Prefers a sun dappled or high open shade. Plant in a location protected from strong winter winds. Good soil drainage is essential (doesn’t like “wet feet”). Poor drainage inevitably leads to root rot, therefore raised beds/plantings should be considered in heavy clay soils Shallow, fibrous root systems (do not cultivate around plants) will benefit greatly from a mulch (e.g., wood chips, bark or pine needles) to help retain moisture and stabilize soil temperatures.
