Special Attributes
 
‘Delaware Valley White’ is a spectacular hybrid evergreen azalea that produces LOADS of funnel-shaped white flowers in spring that nearly covers the attractive green foliage. Each flower has 10 stamens! While the hybridization is unknown, some say this cultivar is a Glenn Dale Hybrid. 



Landscape & Garden Uses

Growing to 3 to 4 feet tall and wide,  Delaware Valley White Azalea is a perfect choice for groupings, mass plantings, low hedges or an accent in partially shaded landscape borders, woodland gardens, and home foundation plantings. Butterflies love the flowers, and blooming branches serve very well for cutting to create stunning indoor floral arrangements.

Spacing:  2.5' for solid hedges;  5'+ for space between plants




Cultural Preferences

Evergreen Azaleas are easy to grow when planted right and in the right spot. They prefer a moist but well-drained and acidic soil that is rich in organic matter and part sun. Morning sun with afternoon shade or filtered sun is ideal. Moderate drought tolerance when established.
