Gray Dogwood
American Sweet Flag

Gray dogwood is a thicket-forming, deciduous shrub with greenish-white blossoms in open, terminal clusters. Young twigs are red and the fruit pedicels remain conspicuously red into late fall and early winter.

Fruit itself is a white, 1/4 in. drupe that usually does not remain on the shrub for long.

Great for naturalizing wild areas, this shrub attracts birds and other wildlife.

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.
