With a name like sea club-rush, you would assume that the plant belongs to the rush family and that it is resistant to salty conditions. Sea club-rush is a sedge. Although it can survive a flood of seawater for a short time, it will die if the flood lasts too long. Sea club-rush prefers to grow with its roots in fresh or lightly brackish water. Various insects live on this plant. Cattle and swine eat the plant and overwintering geese eat the tuberous roots. People even used to ground the sweet-tasting roots for flour.

The leaves have translucent dots but no marginal black glands. Flowers are pale yellow and sometimes red-veined borne in a lax many flowered panicle. The sepals are covered in tiny black spots.
