American Sweet Flag vs Bristly Black Currant

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.

Bristly Black Currant is a native deciduous shrub that grows in moist forests, swamps, and riparian areas. In summer, it produces clusters of dark purple to black berries that provide food for wildlife, while its reddish-purple flowers attract pollinators. The berries are technically edible and enjoyed by some, but many find them unpleasant and bitter.

Thriving in moist soils and shaded locations, Bristly Black Currant helps stabilize soil and supports diverse habitats. It is valuable for conservation plantings, wetland restoration, riparian buffers, and naturalization projects.

Note: When crushed, the berries are known to release an offensive odour.
