wavyleaf basketgrass

Wavyleaf basketgrass is an exotic, invasive grass that was first found in Maryland in 1997, including parts of Patapsco State Park. It grows in dense patches in wooded natural areas preventing the growth of native plants and trees. The grass spreads quickly by stolons and seed. 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.

Lifecycle: 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.
