Yellow Twig Dogwood

Yellow Twig Dogwood is a small deciduous shrub with attractive, bright yellow bark.

It features delicate white, star-shaped flowers and white fruit. It is often used as a screen, and its wide-spreading roots help stabilize areas experiencing soil erosion.

Yellow Twig Dogwood complements Red Osier Dogwood, and it is a great filler to add winter color to shrub and flower gardens.

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.
