Alisma gramineum
Also called Ribbon-leaved Water-plantain, Grass-leaved water plantain, Narrow-Leaf Water-Plantain, Geyer waterplantain, Grasslike waterplantain, Lanceleaf water plantain, Narrow Leaved Water Plantain
Narrowleaf water plantain is a small aquatic or marsh perennial (often short-lived) that grows rooted in mud or submerged in shallow fresh or brackish water. It needs wet to waterlogged conditions with shallow, nutrient-rich water to thrive.
Alisma gramineum is a small aquatic plant in the water-plantain family. It has several common names including narrowleaf water-plantain, ribbonleaf water-plantain or ribbon-leaved water-plantain, and grass-leaved water-plantain. It grows in mud or submerged in shallow fresh or brackish water in marshy areas.
Alisma gramineum is widespread across temperate and subarctic portions of Asia and Europe and North Africa from France and Libya to China and Yakutsk. It is reported from much of Canada from British Columbia to Quebec, as well as most of the western United States plus New York, Vermont and Virginia. This is an endangered and protected species in the United Kingdom. It was first found in Britain in Worcestershire in 1920, and later beside the River Glen in Lincolnshire. At both sites, populations are small, and vary in size from year to year. It typically grows in shallow, nutrient-rich water at the edge of bodies of water and fenland drains. It is an annual plant, or a short-lived perennial, and the seeds may remain viable for some years, sometimes germinating after the ground has been disturbed.
