Peachleaf 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 Peachleaf Willow is often a multi-stemmed willow that generally grows into a tall shrub. This versatile and useful small tree is often seen in riparian zones and erosion control projects. Wildlife rely on the twigs, foliage and bark for food.

A widely distributed willow species, it's long pointed leaves are dark green on top and pale green underneath. The Peachleaf Willow is the tallest of the native prairie willows reaching 40ft in height.
