Carex buchananii Leatherleaf Sedge / Bronze Upright Sedge is one of New Zealand's most architecturally distinctive native sedges, and a plant that has earned devoted fans in gardens around the world. An appealing native ornamental sedge, it showcases exceptionally fine, bronze-cinnamon leaves with delicate tips that are both bleached and curled, presenting itself as a dense, upright clump typically growing to 60 cm in height and width. Where the cascading Carex comans spills and flows, Carex buchananii stands firmly upright — its narrow, fine, copper-bronze to cinnamon-brown leaves arch only slightly at the tips, catching the breeze in an attractive way that is endlessly watchable in a garden setting.
