Size and Form
Little bluestem is an upright grass that grows from 2 to 4 feet tall. It is a clumping grass.
Little bluestem grows in a wide range of soil types as long as they are not wet. Tolerate of both alkaline and acid soils. Good drought tolerance.
This is a warm season grass, so its most active growth occurs in summer. It will remain standing in winter and can act as winter interest.
Since this grass remains attractive through winter, it should not be cut back until early spring, before new growth begins. At that time, it can be cut down to the ground.

Native geographic location and habitat
The alternate leaves are 1/4 inch wide and 10 to 14 inches long. Foliage color can be varied, with some plants being more green and other more blue-green.
Fall color can also vary from orange to bronze to reddish. The fall color is usually very good.
Flowering occurs in late summer into early autumn. The tiny, green to white flowers occur on spikes. The flowers are wind pollinated.
The small fruit (caryopsis or grains) form along the spikes that held the flowers. The fruit have a fluffy appearance due to white hairs.
