Andropogon gerardi (or gerardii), known commonly as big bluestem, turkeyfoot,[2] tall bluestem,[3] and bluejoint,[4] is a tall grass (family Poaceae) native to much of the Great Plains and prairie regions of central North America and grasslands, savannas and woodlands throughout eastern North America.

Description

This species is tolerant of a wide range of soil conditions. Depending on soil and moisture conditions, it grows to a height of Script error: No such module "convert".. Big bluestem is a perennial bunchgrass. The stem base turns blue or purple as it matures. The seed heads have three spike-like projections. The roots are deep, and the plants send out strong, tough rhizomes, so it forms very strong sod. It blooms in the summer and seeds into the fall.

Ecology

Big bluestem is a late-successional grass in prairie ecosystems. It grows in tall, dense stands that shade out other plant species. The stands grow until disturbance interrupts their spread. It is shade intolerant, but typically regrows after wildfire.

Uses

Agriculture

The grass and its variants are good forage for horses and cattle, and can also be cut and used for hay. The grass is high in protein. While not considered the highest quality native forage found in the United States, it has long been considered a desirable and ecologically important grass by cattle ranchers and rangeland ecologists.

Landscaping

It is cultivated by specialty plant nurseries for its drought tolerance and native status. It is often grown for wildlife gardens, natural landscaping, and grassland habitat restoration projects.

Biofuel

Due to its high biomass, big bluestem is being considered as a potential feedstock for ethanol production.

Symbols

Andropogon gerardi is the state grass of Illinois[5] and Missouri[6] and the official prairie grass of Manitoba.[7]

Nomenclatural notes

USDA GRIN rejects the spelling gerardii and provides reasoning for gerardi as being the correct spelling for the specific epithet of this taxon.[8]
