Azalea ‘Delaware Valley’




Masses of elegant white flowers cover Delaware Valley azalea in April to May, creating a stunning and elegant show. And when the flowers have completed their show for the year, the foliage takes over. Dark green leaves take on a slight bronze hue during the fall and stay on through the winter, maintaining form and presence when other plants freeze back. This compact variety is ideal for creating low hedges or using in mass plantings in shady gardens. If you live in a warmer climate, plan to give it more dappled shade (particularly in the afternoon), while cooler areas can give it more sun to ensure healthy growth. Azaleas need moist and enriched soil but be sure it’s also well-drained to avoid rotting. When they’re done blooming in the spring, it’s time to give them a bit of a pruning and fertilizing to make sure next year’s bloom is just as strong.
