Cyperus albostriatus, commonly known as White-striped Flatsedge, is a perennial herbaceous plant native to wetlands and seasonally flooded areas in southern Africa, including Mozambique, Zambia, and South Africa. It typically forms dense clumps reaching 12 to 18 inches (30 to 45 centimeters) in height. This sedge is characterized by its green, grass-like leaves with distinctive white stripes running along the length, and its inflorescences consist of small, clustered spikelets that are not particularly showy. Flowering occurs in the warm months, and while the flowers are not prominent, the striped foliage provides visual interest throughout the year.

White-striped Flatsedge is valued for its striking variegated foliage, which can add texture and contrast to water gardens, bog gardens, and other moist cultivation areas. It is often used as an ornamental plant in wetland restorations and can be effective in controlling erosion along waterways. Cyperus albostriatus prefers full sun to part shade and requires consistently moist to wet soil conditions. It is relatively low-maintenance but may need to be managed to prevent it from becoming too dominant in a garden setting. Gardeners should be aware of its potential invasiveness outside its native range and ensure it is not a prohibited species before planting.CC BY-SA 4.0
