This species is tolerant of a wide range of soil conditions.
Depending on soil and moisture conditions, it grows to a height of
1-3 metres (3.3-9.8 ft). 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.
