Paspalum pilosum, commonly known as Crowngrass, Hairy Paspalum, or Hairy Sandgrass, is a perennial grass that thrives in a variety of moist habitats, including wet meadows, marshes, and the edges of water bodies such as streams and ponds. It is native to a broad region that encompasses the United States, Mexico, and parts of Central and South America. This grass typically reaches a height of 1.5-3 feet (0.46-0.9 meters) and spreads 0.5-1 feet (0.2-0.3 meters) wide, forming tufted clumps with a moderate growth rate. The leaves are notable for their hairy texture, which can help with water retention. Paspalum pilosum produces yellow, inconspicuous flowers during the summer, which are not particularly showy but serve an ecological role by providing forage for wildlife.

Crowngrass is valued for its ability to stabilize soil and prevent erosion, especially in wet areas. It is often used in restoration projects, as ground cover in moist garden areas, and for erosion control along waterways. It is adaptable to various soil types, including clay, loam, and sandy soils, and prefers medium to high moisture levels. While it does best in full sun or part shade, it is also tolerant of a range of light conditions. Gardeners should be aware that in ideal conditions, Paspalum pilosum can spread vigorously and may require management to keep it within bounds. It is generally free from major diseases but can be susceptible to rust in some conditions.CC BY-SA 4.0
