Variegated Dogwood
American Sweet Flag

Variegated Dogwood is a small shrub that is often used in the first row of a shelterbelt, as a hedge, or for soil stabilization projects. It has the same distinctive red bark, white flowers, and berries as Red Osier Dogwood.

The key difference between the two is the leaves. Where Red Osier's leaves are green throughout, Variegated Dogwood has a white outline around each leaf, giving this shrub a distinctive look.

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.
