White Lights Rhododendron (Azalea)

Lewis Mock Orange is a flowering ornamental shrub that produces an abundance of white, fragrant blooms. The flowers have a sweet scent similar to orange blossoms, with a hint of pineapple. They bloom for several weeks from late spring to early summer, attracting pollinators and other beneficial insects.

Native to North America, Lewis Mock Orange is found from the southernmost portions of Alberta and British Columbia, and south into the northwestern United States. It makes an attractive shrub and can be used in hedgerows, pollinator gardens, and naturalization projects. Blooms occur on the previous year’s wood, so it is recommended to prune after it has finished flowering.

White Lights Rhododendron is part of the Northern Lights Series, cold hardy, and deciduous. In late spring you'll be drawn to its fragrant white blooms. In fall, the foliage turns a beautiful purple-bronze color. Pruning is recommended after the flowers are spent to control the size and shape of this shrub.

White Lights Rhododendron should be your next hedge/screen, or plant it on its own as a specimen plant.
