Calamovilfa longifolia
Prairie sandreed is a tall, native warm-season perennial grass of North American prairies and sandy plains that spreads by rhizomes to form sod. It is grown mainly for erosion control and restoration in dry, sandy sites.
Calamovilfa longifolia is a species of warm-season grass known by the common names prairie sandreed and sand reedgrass. It is native to North America, where it occurs from the Northwest Territories to Ontario in Canada and as far south as New Mexico and Kansas in the United States. There are two varieties, var. longifolia being widespread in the species' range and var. magna being native to the Great Lakes region.
This species is a perennial grass with long, leafy rhizomes which hold the soil, forming sod. The roots may reach 3 metres (9.8 feet) deep in the soil. The stems are up to 2.4 m (7.9 ft) tall and can form colonies up to 8 m (26 ft) in diameter. Each stem has up to 12 leaves up to 76 centimetres (2.49 feet) long by 1 cm (0.39 in) wide. The leaves tend to roll up during dry conditions. The inflorescence is a panicle up to 78 cm (31 in) long. The spikelet is pale and shiny.
