Sunset on the Grass 5: Flint Hills, Kansas: photo by Dennis Toll, 2008
The big bluestem has roots six feet deep.
Indian grass grows with the bluestem;
switch grass also ripples there in the wind.
Going west you get less rain:
the little bluestem grows waist high, and so does
the side oats grama, and the bearded needlegrass.
Further west, the short grass of the Plains grows:
the blue grama, knee high; and the buffalo
grass, which grows up to the ankles.
