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. And 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 brackish water. Various insects use this plant as their food source, such as a specific hoverfly and digging wasp. Cattle and swine like to eat the plant as well. Overwintering geese eat the tuberous roots. And even people used to consume sea club-rush: the sweet-tasting roots were ground for flour.
