Planting in and around ponds, streams, or low marshy areas is recommended, especially given that needle spikerush can tolerate almost complete submersion. The needle spikerush is intolerant of drought conditions and should be planted near a ready source of water. Needle Spikerush Growth, Hardiness & Climate Needle spikerush thrives best in loamy, sandy, or silty soil. In the rare event that growth becomes an issue, it can be trimmed back to a preferable height with no detriment to the plant itself. The short stature of the needle spikerush makes it an ideal form of ground cover. There are several forms of insects that consider the needle spikerush a viable food source, but it is not considered at risk for any major pests, infestations, or floral diseases.įor the cultivation of gardens, the needle spikerush can aid in anchoring the soil and providing a dense, relatively short carpet of foliage along the edge of water-based elements. Propagation through both seeds and long fibrous root systems make it resistant to most natural concerns. acicularis is a hardy plant with a fairly quick growth rate. The foliage and roots also serve as a food source for wetland mammals, notably the muskrat.Į. The seed-heads also provide food for many species of marsh or wetland birds such as ducks, rails, coots, and geese, including the Canadian goose. Entomologists with an interest in wetlands insects consider the needle spikerush a valuable aid in observing some of the rarer species of leaf cutters and leaf beetles. Among the insect consumers are several variants of leafhoppers and leaf beetles, as well as caterpillars of the yellow-collared scape moth ( Cisseps fulvicollis). Leaves, stems, and seed-heads provide food for a number of creatures. The needle spikerush is most often used to stabilize shorelines, especially those with a high percentage of sand or silt. For this reason, they can be used for a variety of purposes. acicularis thrives in marshy areas with plenty of water available. Bernard DUPONT from FRANCE, CC BY-SA 2.0, via Wikimedia CommonsĮ. Facts, Benefits & Uses of Needle Spikerush The leaves, stems & seed-heads of the needle spikerush provide food for a number of creatures, including this green leafhopper. These stems form colonies, which in turn form a dense carpet of growth.
The lowest of these florets eventually forms the flower from which a single achene, or seed, emerges. This spike is further covered with a number of scales, from which florets emerge, arranged in a spiral. The stem itself is topped by the slightly flattened lance-tip style spike from which the plant derives its name. Two thin, bladeless leaves are formed on either side of the stem, narrowing down to a papery sheath at the base. The needle spikerush is recognizable by the configuration of its leaves and stems. This plant generally grows in clumps and is well-liked for its ability to form a dense, lush carpet in a relatively short time frame. The stems rarely grow beyond the height of 4 – 6 inches. One of its defining features is its relatively short stature. The needle spikerush resembles many other plants of the sedge family. In this case, our focus is on the terrestrial plant most commonly identified as E. Others favor the stance that the underwater variety, known as hair grass, is actually a different species of spikerush: the dwarf spikerush ( E. Some botanists and botanical resources claim the plant has two distinct variants, one terrestrial and one which grows in an entirely submerged environment. There is some debate among the botanical community in regards to E. It is considered one of the most common variants of spikerush found in the world.
Needle spikerush is native to North America, parts of South America, Europe, and south-eastern parts of Asia. This family includes many different types of plants, most notably bulrushes and cottongrass ( g. It is one of 16 known members of the Eleocharis species, and is further classified under the broad-ranging Cyperaceae(sedge) family. The Eleocharis acicularis is known not only as the needle spikerush, but also the least spikerush. It works well for rain gardens, ponds, or any wetland-style arrangement.

(UK & US) Needle spikerush is a member of the sedge family and usually grows in clumps.
