quackgrass
Invasive lawn pest
Quackgrass is a persistent weedy grass with creeping underground stems that spread aggressively through lawns and gardens.
Its root system makes it notoriously difficult to eradicate—pulling it up often leaves fragments that regenerate.
Also called couch grass or witch grass: The quackgrass has taken over the back corner of the yard.
