Lewis Mock Orange

Diablo Ninebark is a small, low maintenance, multi-stemmed shrub, that is used to add texture or color to any yard. This plant grows dark purple leaves in the spring and grows slightly faster than Common Ninebark. It features flaky red to brown bark, clusters of white flowers, and long, maple-like leaves. Diablo Ninebark can make a dense and colorful hedge, or it can be an attractive ornamental by itself.

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.
