American Sweet Flag
Golden 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.

Golden Willow is an attractive accent tree that's perfectly suited for those moist or wet areas on your property.

This fast growing tree has glossy narrow leaves that turn gold in fall, furrowed brown bark and showy gold branches that especially stand out in the winter.

Golden Willow is commonly used for windbreaks, shelterbelts, and ornamental planting. In addition to looking great, Golden Willow attracts a variety of birds and mammals with its twigs and buds.

All willow are important to native pollinators each spring as they have higher amounts of pollen and nectar early each growing season when other food sources are scarce.

Note: do not plant near buildings or buried services.
