Native to Europe, central and southeastern Asia, North America and northeastern South America.Cut any wandering stems in the spring to control plant growth.Keep an eye out for species of leaf beetles and leafhoppers in the wild. Requires little care, is virtually disease-free and pest-free.It is suitable for small, medium and large ponds and can be grown as a fully submerged aquatic plant in outdoor ponds or in aquariums. This plant can be grown near ponds and streams, in bog gardens, or as a ground cover.Can also be planted in standing water to 12 in. Performs best in full sun in acidic to slightly alkaline, wet soils.This plant will spread by creeping rhizomes to form a colony if not restrained. Needle Spikerush is also ideal for natural ponds to help prevent soil erosion. It can also absorb mineral salts from the water and reduce algae growth. The submerged leaves give off bubbles of oxygen, improving the water quality and maintaining the eco-balance of the pond. Usually, it is grown as an oxygenating plant from the bottom of ponds or water features. Growing from rapidly spreading rhizomatous roots, it can form dense mats considered good habitat for fish to lay their eggs. Native to Europe, central and southeastern Asia, North America and northeastern South America, Needle Spikerush is a plant of marshes, vernal pools, and bogs, and it is also a popular aquarium plant. Submersed plants tend to be strictly vegetative, lacking spikes, and the stems can grow significantly longer than terrestrial plants, depending on the water depth. The tiny flowers are borne at the tip of each stem in single, sharply pointed, tiny spikelets. In shallow water it will form short spikes of tiny flowers amongst flat overlapping leafs. Houseplants are sometimes sold as Dracaena 'Spikes'.Eleocharis acicularis (Needle Spikerush) is an aquatic or marginal, annual or perennial boasting very thin, grass-like stems arising from a creeping rhizome. It has thin, grass-like colorful leaves that arch in a fountain-like growth habit. It grows to be quite a large tree in its native habitat, but immature plants are often used as houseplants. Cordyline australis(cabbage palm) is often sold as Dracaena, since the plant was initially categorized under that genus.It has colorful lance-like leaves that arch from the base. Cordyline fruticosa (cabbage tree, ti tree, or ti plant) is a palm-like plant with thicker strappy leaves that emerge in a fountain-like arrangement atop one or more thin woody stems.This is a familiar novelty plant that may be kept only a few inches tall, or grown to several feet in height. Dracaena sanderiana (lucky bamboo) is often trained to have curled stems by careful manipulation of the direction of sunlight.Dracaena marginata ( dragon tree) has thinner, grass-like leaves that fountain off of multiple thick stems. Outdoors in zones 10 to 12, these plants can reach a large size, but when grown in pots they generally remain under 10 feet. In their submersed, free-floating form, though, they are a tangle of long thin branches. Emersed, they look like but small but normal spikerushes. Road-grass, and two or three other species, are also known as the so-called viviparous spikerushes.
