Pussy Willow

Pussy Willow is a large shrub or small tree that produces catkins that are soft, silky, and silvery before leaves appear in the spring. This native willow prefers moist to wet soil.

Pussy Willow makes a beautiful accent tree, and its bright branches can be used for floral arrangements or basket making.

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.

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.
