Water grasses in a swamp.
Watergrass is grass that grows well in an aquatic environment. Some grasses are truly aquatic, preferring to grow in water and mostly being submerged in water, while others like soggy soil or shallow water and can tolerate dry land. Aquatic grasses can be found throughout the world, with several species of grasses surviving well in water. Reeds are a particularly notable example of aquatic grasses.
Some people like to grow aquatic grass as an ornamental if it has water features. Grasses can dramatically change the appearance of a pool, pond, stream, or similar feature, adding color and texture to the landscape. They can also be used to reduce the risk of flooding, as the grass helps control water levels. Many of these grasses provide habitat for animals and birds. Planting watergrasses can attract waterfowl to a garden, in the same way that natural watergrasses in wet, marshy areas are an important part of the ecosystem.
Aquatic grasses can also be grown for commercial use, from animal feed to flood control. Historically, watergrasses have been used for crafts such as basketry and furniture, and are also used to make ornamental crafts. Habitat restoration in wetlands classically also includes the establishment of native aquatic grasses to restore balance to the area. As well as being established by people, of course, aquatic weeds grow wild in the natural environment.
In some cases, watergrass can become invasive. An introduced species can suffocate the natives, reducing biodiversity and threatening the balance of the environment. Some non-native species may actively discourage the establishment of aquatic organisms, which will drive away waterfowl, and others will become a commercial problem, becoming entangled in aquatic equipment such as boats. Concerns about invasive species have led many garden organizations to recommend that gardeners work with native species when planting ornamental aquatic grasses, to prevent the spread of non-native plants.
Watergrasses come in all styles and colors. Some have long, upright stems that protrude from the water, while others develop a habit of growing slowly, floating on the surface of the water. The grass can be green, blue or yellowish, and some flowers and seeds at various times of the year. Aquatic grasses can be propagated through seeds, cuttings, and split root clods. Gardeners looking to establish aquatic grass can explore options at a local nursery. Employees may have specific recommendations for customers along with tips on managing invasive aquatic grasses.
