Other Names:
Prairie Wedgescale
Prairie Wedgegrass is a perennial grass in Northern Virginia and a few other parts of the state. It can grow in many types of habitats, such as prairies, marshes, dunes, and disturbed areas. It spreads by reseeding itself, and its blooming period is from the late spring to the middle of the summer. Grasses, sedges, and rushes are often confused. They are in three different families, and a mnemonic for remembering the differences is "Sedges have edges, rushes are round, and grasses have nodes from the top to the ground". The nodes are the raised places on a grass stem, and they are less obvious on sedges and rushes.
