Lewis Mock Orange
Golden 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.

Golden Lights Rhododendron is an exceptionally cold hardy, deciduous azalea. Part of the Northern Lights Series, this shrub was cultivated specifically to withstand harsh winters, making it ideal for our prairie climate.

In late spring you'll be drawn to its beautiful, golden, sweetly fragrant flowers. Pruning is recommended after the flowers are spent to control the size and shape of this shrub.

Consider Golden Lights Rhododendron when planning your next hedge, or plant it on its own as a striking specimen plant.
