This grass-like rhizomaceous perennial that can be found growing in standing water is an excellent choice for water gardens, bogs, pond edges and other wet areas. It forms clumps of twisted and curled green leafless stems that add a touch of whimsy or unkept look, depending on your point of view. The upright cylindrical tighly twisted stems form clumps as they uncoil and grow upward as well as ourward. Green during the growing season, the stems turn brown in the fall. Small tan or yellowish-green flowers may be produced in compact clusters in summer but are not ornamentally significant. Because of its tendency to spread, corkscrew rush is best grown in a container that confines its root system. The container can be sunk in the mud of a pond with the water level a couple of inches above the rim of the pot. Plants can also be grown in pots but will require frequent watering. Stems are attractive in floral arrangements.
