The sedges are usually found growing outdoors in boggy soil at the sides of rivers and ponds, but one variety, Carex morrowii ‘Variegata,’ makes a useful houseplant.
The narrow, grassy leaves, striped pale green and white, arise from a rhizomatous root to make a gracefully arching fountain of foliage up to 18in/46cm long.
Plants are easy to grow and are not fussy about conditions, although they prefer a cool, humid atmosphere. They are useful plants for groups, where their slender, upright, grassy foliage contrasts well with broad-leaved plants that have more rounded shapes.
