Green Bulrush vs American Sweet Flag

Green Bulrush is a common waterside plant, suitable for erosion control and land reclamation. Despite this, Green Bulrush is very drought resistant once established. Bulrushes can cool nearby areas on hot days.

Unlike many of the other waterside plants available, Green Bulrush does not attract wildlife. This makes it a good choice for surrounding residential water sources.

Green Bulrush is topped with spiky balls of florets, green in the spring and fading to brown in the fall.

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.
