Lewis Mock Orange

Twinflower is a native, trailing evergreen ground cover known for its delicate flowers that grow in nodding pairs. These pale pink blooms are described as being sweetly fragrant, attracting native bees and other pollinators.

Growing in cool, moist, acidic soils, the trailing stems form roots as they spread and start to form mats across the forest floor. Due to its woody stem, it is technically classified as a shrub and often referred to as a subshrub or dwarf shrub. This species is well-suited for naturalization, restoration, and conservation projects.

Twinflower (Linneae borealis) was named in honour of Carl Linnaeus, who adopted it as his personal emblem.

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.
