Wavy-leaved Basketgrass is an invasive species from Asia that is fast becoming established in Maryland. Its initial discovery in Maryland was in 1997, by botanist Edward Uebel, in Patapsco Valley State Park.
This perennial grass is easy to identify because it has distinct ripples across the width of the leaf blade. The plant begins to flower in July and fruits appear in late summer. The fruits are easily spread because they are sticky and cling to clothing, dogs, and large wildlife.
Since its discovery along the Patapsco in 1997, Wavy-leaved Basketgrass has spread to many of the bottomlands of the Maryland Piedmont. As of 2020, it was well established throughout the Piedmont and along the Fall Line, and it was springing up in the Ridge and Valley Province and had been spotted at a few sites on the Coastal Plain.
