Carex nigra - Black Sedge
Black sedge can be grown in moist to wet soil or in very
shallow water. It is tolerant of full sun as long as it
is constantly wet. However under drier conditions it requires
shade and in part shade the colour will be better. It is
a widely variable species. Ours probably originated in North
America.
