This plant is called a White Lights azalea because of its white flowers and because this plant was one of a group that were developed to survive very cold winters and were called the 'Northern Lights' azaleas.
White Lights azalea is a multi-stemmed deciduous shrub that grows slowly, reaching a final height and width of about 5 feet. White Lights is completely smothered in pinkish-white fragrant blossoms in mid-spring. Like most azaleas, it prefers a partly shaded site, with protection from afternoon sun, such as on a northerly or eastern frontage. It requires a rich acidic well-drained, but consistently moist soil and will demonstrate chlorosis (leaf yellowing) in alkaline soils. Prune immediately after flowering and mulch the root zone in the fall for winter protection.
