Eleocharis Quadrangulata- Four Square Rush
Eleocharis Quadrangulata, also known as Four Square Rush or Four Angle Spikerush, is an approximately two to four-foot tall rush that grows at the edges of freshwater bogs, rivers, streams, lakes, ponds, and other slow-moving or standing water. It is rarely submerged. This rush gets its name from its dark green sponge-like stems, which are nearly square-shaped. This perennial herb is native to both the central and eastern parts of North America as well as west-central parts of Mexico. Its hardiness zones range from zone 3 to zone 11. Found in California, Oregon, Wisconsin to Massachusetts, Tennessee, and Florida. The plant is considered endangered in the United States. The Four Square Rush has a moderate growth rate and will take approximately twenty years to reach its full height. At the end of spring to early summer, the rush blooms small clusters of green perianth bristles with brown bracts on every single spikelet. Each plant has a spread of one to two feet. The plant grows upright, with a small bend to its stem. Its leaves are tube-shaped sheaths at the base of each stem. This rash tends to increase densely in shallow areas. The fruit of the plant is one low seed that remains closed. This rush belongs to the Poales order within the Monocot group and Cyperaceae (or Sedge)family of plants. Its active growth period is from spring until fall and adapts to fine, medium, and coarse-textured soils. It has a root depth of about eight inches and can propagate by either seed or bare roots, which are rhizomatous. The Four Square Rush prefers full sun but can tolerate a mild amount of shade. The Four Square Rush provides erosion control and bioremediation to help decrease pollutants. The rush is hardy and will desiccate only in the driest months.
