English term (edited): perennial rhisomatous grasses

Rhizomatous grasses spread below ground stems known as rhizomes (Fig. 2). These rhizomes terminate in a shoot that emerges some distance from the mother plant. As these new shoots mature they will also produce rhizomes that eventually produce new shoots thus creating a lawn. Healthy, vigorous rhizome type grasses such as Kentucky bluegrass tend to form dense, uniform lawns with shoots oriented in an upright position.
