The Water Horsetail (Equisetum fluviatile), also known as the Swamp Horsetail, is a perennial horsetail that commonly grows in dense colonies along freshwater shorelines or in shallow water, growing in ponds, swamps, ditches, and other sluggish or still waters with mud bottoms. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for A perennial plant or perennial ( Latin per, "through" annus, "year" is a Plant that lives for more than Equisetum is a genus of Vascular plants that reproduce by spores rather than seeds A swamp is a Wetland featuring temporary or permanent inundation of large areas of land by shallow bodies of water It is a herbaceous species, growing 30-100 cm (rarely 140 cm) tall with erect dark green stems 2-8 mm in diameter, smooth, with about 10-30 fine ridges. A herbaceous plant (or in botanical use a Herb) is a Plant that has leaves and stems that die down at the end of At each joint, the stem has a whorl of tiny, black-tipped scale leaves 5-10 mm long. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. Many, but not all, stems also have whorls of short ascending and spreading branches 1-5 cm long, with the longest branches on the lower middle of the stem. The side branches are slender, dark green, and have 1-8 nodes with a whorl of five scale leaves at each node. The Water Horsetail has the largest central hollow of the horsetails, with 80% of the stem diameter typically being hollow.
The stems readily pull apart at the joints, and both fertile and sterile stems look alike.
The Water Horsetail reproduces both by spores and vegetatively by rhizomes. In Biology, a spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions In Botany, a rhizome is a horizontal stem of a Plant that is usually found underground often sending out Roots and Shoots It primarily reproduces by vegetative means, with the majority of shoots arising from rhizomes. Spores are produced in blunt-tipped cones at the tips of some stems. The spore cones are yellowish-green, 1-2 cm long and 1 cm broad, with numerous scales in dense whorls.
The Water Horsetail ranges throughout the temperate Northern Hemisphere, from Eurasia south to central Spain, northern Italy, the Caucasus, China, Korea and Japan, and in North America from the Aleutian Islands to Newfoundland, south to Oregon, Idaho, northwest Montana, northeast Wyoming, West Virginia and Virginia.

This horsetail is sometimes seen as an invasive species because it is very hardy and tends to overwhelm other garden plants unless it is contained. Introduced species|Weed Invasive species is a phrase with several definitions When planting, it is best to plant them with the rhizome in a container.
The Water Horsetail is most often confused with the Marsh Horsetail E. Equisetum palustre, the Marsh Horsetail, is a plant species belonging to the division of horsetails ( Equisetophyta) palustre, which has rougher stems with fewer (4-8) stem ridges with a smaller hollow in the stem centre, and longer spore cones 2-4 cm long.
Uses
The Water Horsetail has historically been used by both Europeans and Native Americans for scouring, sanding, and filing because of the high silica content in the stems. For indigenous peoples in the United States other than Hawaii and Alaska see also Native Americans in the United States. The Chemical compound silicon dioxide, also known as silica or silox (from the Latin " Silex " is an Oxide Early spring shoots were eaten. Medically it was used by the ancient Greeks and Romans to stop bleeding and treat kidney ailments, ulcers, and tuberculosis, and by the ancient Chinese to treat superficial visual obstructions. The kidneys are complicated organs that have numerous biological roles Ulcers are healing wounds that develop on the skin mucous membranes or eye Tuberculosis (abbreviated as TB for tubercle bacillus or T u' b' erculosis Bacillus --> is a common Rootstocks and stems are sometimes eaten by waterfowl.

According to Carolus Linnaeus, reindeer, which refuse ordinary hay, will eat this horsetail, which is juicy, and that it is cut as fodder in the north of Sweden for cows, with a view to increasing their milk yield, but that horses will not touch it.
