About Ticklegrass (Agrostis scabra) Agrostis scabra is a common species of grass known by the common names rough bent grass and ticklegrass. A tumbleweed, it is native to much of North America, and widely known elsewhere as an introduced species. It occurs in most of the United States except parts of the Southeast and most of Canada except for the farthest northern regions. It can be found in Mexico, and across Alaska to far eastern Asia as far south as Korea. It is resident in a great variety of habitats, from warm coastal valleys to the alpine climate of high mountain ranges. This is a perennial grass growing mainly upright in form to heights around 75 centimeters. The leaves are rough with tiny hairs and up to about 14 centimeters long. The flower cluster is a wide open array of spreading, thready branches bearing spikelets each a few millimeters long. The tolerance of this grass to alpine climates makes it a good plant to use in revegetating disturbed land in such regions. It is known to spring up on sites where few other plants can grow, such as abandoned coal mines and soils polluted with sulfur, copper, and nickel.
