Lewis Mock Orange
Round Leaf Hawthorn

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.

Getting its name from rounded, toothed leaves, the Round Leaf Hawthorn is a winter hardy shrub that grows small, red, berry-like fruits.

Commonly used for landscaping, this shrub can also be found along stream banks and in wooded areas. Caution is advised when handling the Round Leaf Hawthorn, as it can have sharp thorns approximately 1" long.
