Eleocharis acicularis is an annual or perennial spikesedge with long, grasslike stems to about 15 centimeters (6 inches) in height, shorter in bog conditions, from a creeping rhizome. In shallow water it will form short spikes of tiny flowers amongst flat overlapping bracts. The tiny flowers are less than five millimeters in diameter and are borne at the tip of each stem in single, sharply pointed, lanceoloid spikelets up to about six millimeters long. This is a plant of marshes, vernal pools, and bogs.[4]
Eleocharis acicularis is sold commercially as an aquascape plant suitable for inclusion in artificial aquatic environments. It thrives with plenty of light and a high concentration of carbon dioxide.[5][6]
