Physical description: Big bluestem grass is a tall perennial bunch grass
that forms large erect clumps of stems with attractive foliage
that changes color seasonally - the leaves that are blue-green
in spring, develop red tinges as they mature in summer, then
turn copper-brown by fall. Reddish cast with lavender tones is
formed after frost. In late summer, flowering stems rise above
the foliage, bearing three finger-like branches resembling turkey
feet that are purplish in color. Big bluestem grass usually grows
to 4-8 feet, but can grow taller in moist soils.
Optimal growing conditions: Big bluestem grass grows well in most growing
conditions with varying moisture/fertility/ pH level of soil,
but it prefers light, moist, fertile soils under full sun. This
plant does not tolerate excessive winter moisture. It develops
an extensive root system that saturates the top 2 ft of soil
and reaches up to 12 ft below ground. Once established, it is
drought-tolerant.
Susceptibility to pests and diseases:
There are no serious pest or disease
problems for Big bluestem.
Use: Big
bluestem is well suited for naturalizing in wildflower meadows
or prairie gardens. It is also good as border, screen, or accent.
This plant also serves as a good grass for erosion control.
