About wavyleaf basketgrass
Wavyleaf basketgrass (Oplismenus undulatifolius) is an exotic, invasive grass that was first found in Maryland in 1997, including in parts of Patapsco State Park. As of 2020, it has been established throughout the Piedmont region of Maryland.
This invasive weed grows in dense patches in wooded natural areas preventing the growth of native plants and trees. The grass spreads quickly by stolons and seeds. The seeds are easily moved around by people and animals because they are sticky and adhere to shoes, clothing, tires, animal fur, and paws. Stay out of areas and do not let dogs run in stands of wavyleaf basketgrass in late summer and fall to help prevent seed dispersal.
Life cycle
Invasive shallow-rooted perennial grass
Growth habit
Develops elongated stolons (stems) that root at the nodes (where growth occurs) along the ground. Can grow to 18". Hairy stems.
Reproduction
Seeds and stolons. Spikelet flowers. Seeds mature in late September through frost.

Management
Prevent this plant from going to seed. Hand-pulling or digging out the plants is the preferred method of removal, to protect native vegetation that may be interspersed. Wavyleaf basketgrass has a very limited root system and pulls out easily, especially when the soil is moist. Focus on removal in high-traffic areas first, to limit dispersal by seeds. Do not compost plants with seed heads.
