Little Bluestem, Big Bluestem, Indiangrass, and Switchgrass are the legendary "Four Horseman" of the Tall Grass Prairie. These species are the nucleus of the prairiegrass ecosystem that once covered most of the central plains of North America. They are all excellent forage producers that make forage "nature's way" without planting invasive, introduced grass species which require expensive inputs . They are well adapted to both upland and lowland sites. The 'Big 4' are the workhorse native grasses which are heat and drought tolerant and will provide permanent cover and forage production. The 'Big 4' Mix is big on performance and value.
