Alberta Wild Rose (Prickly Rose)

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.

Alberta's provincial flower, Alberta Wild Rose, is a small, deciduous shrub known for its beautiful pink blooms and thick, thorny stems.

Native to Canada, this hardy perennial is an attractive addition to any garden. Wildlife enjoy its edible rosehips, which inclined growers can use in jams, jellies, and rose hip tea.
