Lewis Mock Orange

Common Caragana is a fast growing shrub that's known for its exceptional hardiness and drought tolerance. Although it's most commonly planted in shelterbelts, Common Caragana is also an excellent hedge or feature shrub.

Note: in warmer areas, this species can be difficult to contain once planted. Use the right plant in the right place.

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.
