Lawn grasses, bunch and creeping
Once out of the seedling stage, grasses may grow primarily upward (bunch type) or outward (creeping type).
Bunch-type grasses are named for their bunchy appearance, caused by the production of many tillers from the crown of the plant. These grasses expand only by tillering.
Creeping-type grasses are named for their creeping growth habit. These grasses spread by stems that stretch out from the crown of the plant. New shoots develop from nodes on underground stems, called rhizomes, or on horizontally growing aboveground stems, called stolons.
