IPM1007, Revised November 2009
Summer annual grass
A densely hairy, erect summer annual grass that may reach as much as 32 inches in height. Seedlings and mature plants have leaves that are covered with hairs on both surfaces. Leaves are rolled in the bud, lack auricles and have a ligule that is a fringe of hairs often fused at the base. Ligules are usually 1 mm but may reach 2 mm in length. Leaf blades have a conspicuous white midvein and are from 4 to 10 inches long, 5 to 15 mm wide. Sheaths are erect and also covered with hairs. The seedhead is a dense panicle that eventually becomes open and may range from 8 to 16 inches in length. Panicles may account for as much as half of the entire height of the plants.
