Bunch grass
From Wikipedia, the free encyclopedia
Also commonly called tussock, bunch grasses are any grass that grows in clumps or tufts, rather than forming a sod or mat. As perennial plants, they live more than one season. With long roots that may reach two metres into the soil, bunch grasses can find water where other plants wither.
Bunch grasses occur in almost any habitat where grasses are found including deserts, wetlands, savannas, forests and tundra.
