Orange New Zealand Sedge (Carex testacea), also known as Orange Sedge or Prairie Fire Sedge, is a colorful ornamental grass native to New Zealand. Part of the Cyperaceae family, it forms graceful, arching clumps of fine, hair-like foliage that shifts from olive green to vibrant orange and copper tones, especially when exposed to sun and cool weather. This warm-toned transformation makes it a striking choice for year-round visual interest in landscapes.

Typically found in coastal regions, sand dunes, and open grasslands, Carex testacea is well-adapted to windy and rugged environments. It remains compact and low-growing, often used for mass plantings, borders, or container arrangements where its texture and color create dynamic contrast with other plants.

Unlike many grasses, its changing seasonal hues are a defining feature, enhancing autumnal palettes and modern garden compositions. Its tidy habit, movement in the wind, and adaptability make it a standout among ornamental grasses.
