American Sweet Flag
Golden Weeping Willow

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.

The Golden Weeping Willow is a cultivar with bright yellow twigs and an attractive weeping shape. It is one of the most popular willows, with high ornamental value.

The Golden Weeping Willow has glossy green foliage during the spring and summer months, then the leaves turn a golden-yellow in the fall. The brown bark is furrowed and the overhanging branches keep their yellow tone, so they also have significant winter interest.
