Carex buchananii, commonly known as Buchanan’s Sedge, is an evergreen perennial grass native to the open grasslands and rocky outcrops of New Zealand. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), forming dense tufts of fine-textured, coppery-brown foliage that provides year-round interest. The plant’s inflorescences are subtle, with brown flower spikes appearing in summer, which are not particularly showy but add to the plant’s texture.

Buchanan’s Sedge is valued for its unique color and texture, which can add contrast to garden compositions. It is often used in ornamental plantings, mixed borders, and as a container plant. It is relatively low maintenance, tolerating a range of soil types, though it prefers well-drained soils. It can handle full sun to part shade and requires moderate watering, with reduced watering needs once established. While generally disease-free, it can suffer from root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
