Big Bluestem Grass, also known as Andropogon gerardii, is a perennial grass native to North America. It is a dominant species of the tallgrass prairies and is widely distributed across the central and eastern parts of the United States and Canada. Big Bluestem Grass is a warm-season grass, meaning it grows most actively during the summer months when temperatures are warm. It is a highly valued species for its ecological and economic benefits, including its role in soil conservation, wildlife habitat, and forage production.
Characteristics and Growth Habits
Big Bluestem Grass is a tall, bunchgrass that can grow up to 6 feet in height. It has a deep root system, with roots extending up to 10 feet into the soil, which allows it to access water and nutrients during periods of drought. The grass has a blue-green color during the growing season, turning a golden brown in the fall. Big Bluestem Grass is a clump-forming grass, with new shoots emerging from the base of the plant each year. It is a long-lived species, with some plants reported to live up to 50 years or more in ideal conditions.
Habitat and Distribution
Big Bluestem Grass is typically found in areas with well-drained soils and full sun. It is commonly associated with other tallgrass species, such as Switchgrass and Indiangrass. The grass is widely distributed across the Great Plains region of North America, including the states of Texas, Oklahoma, Kansas, Nebraska, and the Dakotas. It is also found in the eastern United States, including the states of Illinois, Indiana, and Ohio. Big Bluestem Grass is a key component of the tallgrass prairie ecosystem, providing habitat and food for a variety of wildlife species, including deer, turkey, and songbirds.
