Square-Stem Spikerush is a Hardy Aquatic Plant that is Low Maintenance

Square-Stem Spikerush-Eleocharis quadrangulata. The Square Stem Spikerush is named for its bright green square-shaped stem, most apparent when the plant is cut in cross-section. Spike rushes area a family of aquatic plants that grow in and around lakes, ponds, rivers, and streams throughout the Midwest and eastern states of the US; it has been introduced to California. It is also common in the wetlands and marshes of Ontario.

Square-Stem Spikerush is a protected species in some eastern states such as Connecticut, Massachusetts, and Pennsylvania.

It is most common along the Mississippi River and less rare in the Midwestern states. Spike rushes grow in large colonies along the water's edge, creating a haven and a micro-ecosystem within the colonies. Invertebrates live under the submerged plants while waterfowl and mammals feed on the plants' seeds, stalks, tubers, and rhizomes. Some species of ducks and geese will nest in the rushes. Deer avoid them.

Square-Stem Spikerush does not Produce Flowers and Attracts Invertebrates, Waterfowl, and Mammals for their Seeds, Stalks, and Tubers

Square Stem Spikerushes are perennials that bloom from early summer to early fall. They do not produce flowers. Instead, they have small green spikelets that range in size from half an inch to two inches. Spike rushes prefer full sun and can reach about four feet high when fully grown. They can be propagated by transplanting rhizomes. Once planted, they can take over wetlands within a few seasons. Care should be taken not to leave any seeds or tubers behind when moving spike rushes, as they can sprout new plants from those, too. It prefers slightly acidic to neutral soil. It grows well in moist soil; however, it is at its best in 6 to 12 inches of water, such as what may be found in a garden pond.
