Common Spikerush - Eleocharis palustris
Common Spikerush – Eleocharis palustris is typically found in lowland tropical wetlands, most often along banks of the water. Small groupings of Common Spikerush can grow as tall as four feet, sometimes entirely submerged underwater. These perennial plants look like tall grass.
The common spikerush is strikingly similar in look to tall grass. But that is perhaps, where its similarities end. These perennial plants don't have any leaves on them, instead of having developed sheath-like implements along their bases which are nutrient rich. One of the critical giveaways that it is spike rush and not a tall grass, are the small fruiting spikes on the tops of all blades. Not much soil is needed to plant this fast growing ground cover, in fact, two to five inches of water is more than adequate to produce full and hearty patches of spikerush.
Common Spikerush is excellent for wetlands.
They do well when planted on the edges of bodies of water or streams as they provide many nutrients to native bird and fish life. The thick clumps and wispy nature of the spike rush mean it can give a right edge to a pond or property line that abuts water. Because of the dense nature of the rhizomes in and along its root system, the spike rush helps maintain excellent water clarity.
The popularity of spikerush with landscapers in lowland tropical and wetlands is unmistakable.
Common Spikerush is a very hardy plant.
A hardy plant that can survive very much on its own and thrive in areas where many others would drown. Not only does this ground covering plant add height to the edges of bodies of water, but it is also almost whimsical when the wind hits it. There is even a bird in Australia that uses the stems and roots of spikerush for much of its nutritional intake. The spikerush is a beautiful addition to anyone looking to liven up water features or streams. Requiring little to no work to maintain is also a plus. Common Spikerush
