Common Spike-rush Eleocharis acuta is a semi-aquatic, rhizomatous perennial sedge with single erect stems to 60 cm high, with a purplish leaf sheath at the base. The hollow rounded stems (culms) are topped by a terminal spikelet 5-30 mm long and 3-7 mm wide, flowering from spring to summer. Common Spike-rush is found in swamps and wet areas. At Venus Bay it is common in wet pasture and along the drainage channel along the Venus Bay to Tarwin bike path.
Spike-rushes provide excellent habitat for frogs and water birds and are attractive on the edge of ponds and wetlands. Shown here is Tall Spike-rush Eleocharis sphacelata.
