Alberta Wild Rose (Prickly Rose)

American Sweet Flag is a native perennial wetland plant found along shorelines, streams, wet meadows, and marshes. Its extensive rhizome system allows it to spread and stabilise soil, helping maintain the edges of ponds and streams. This dense growth provides cover for small animals and supports overall wetland biodiversity, while the rhizomes and seeds serve as food for small mammals and waterfowl. Cold-hardy and resilient, it is well-suited for ecological restoration, riparian plantings, erosion control, and naturalization projects.

The plant grows in dense clumps with tall, sword-shaped leaves that release a citrus-like scent when bruised. The rhizomes are aromatic, with a spicy, cinnamon-like fragrance that has been used in perfumery and flavouring. In early summer, American Sweet Flag produces a distinctive floral spike (spadix), adding visual interest to wetland plantings.

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.
