Cyperus fuscus, commonly known as brown galingale or brown flatsedge, is a perennial herb that is native to marshes, wet meadows, and the edges of water bodies in Europe, Asia, and North Africa. It is typically found in seasonally wet areas that may dry out in summer, such as ditches and temporary ponds. This plant is well-adapted to fluctuating water levels and can often be found in disturbed wetlands. Cyperus fuscus is a relatively small sedge, usually reaching up to 10-40 cm in height, with a tufted habit and distinctive brownish-green spikelets that appear from July to September. The flowers are not particularly showy, but the plant has a neat, grass-like appearance that can be attractive in a naturalistic planting.

Brown galingale is valued for its ability to thrive in wet conditions and can be used for soil stabilization along pond edges and in rain gardens. It is also of interest for creating wildlife-friendly areas, as it provides habitat for aquatic insects and birds. In cultivation, it prefers full sun to part shade and requires consistently moist to wet soil. While it is not commonly grown in ornamental gardens, it can be a useful plant for ecological restoration projects and naturalized water features. Care should be taken when growing Cyperus fuscus outside its native range, as it has the potential to become invasive in some regions.CC BY-SA 4.0
