Carex is a genus of sedges, which indicates that they form tight clumps of grass-like leaves. Many of the cultivated kinds have bronze or variegated foliage, and if clumps are split and replanted they soon make useful ground cover, giving structure and subtle colour throughout the year.

Carex morrowii 'Variegata' is a good variegated sedge with light green and golden cream grassy leaves, forming a low clump of arching or cascading evergreen leathery leaves. It originates from Japan, and can be used as a choice plant for edging.
