American Sweet Flag vs Wheat Sedge

Wheat Sedge is a native perennial sedge commonly found in wetlands, ditches, and along shorelines. It thrives in saturated soils, spreading by rhizomes to form large colonies that stabilize both soils and shorelines. This makes it valuable for wetland and riparian plantings.

Its distinctive, wheat-like seed spikes add seasonal character while providing food for waterfowl, and its dense clumps supply cover and nesting habitat for birds and small animals. Together, these traits make Wheat Sedge an important species for enhancing biodiversity and supporting healthy wetland ecosystems.

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.
