The story
Switchgrass was one of the big four grasses of the tallgrass prairie, with roots that reach ten feet down. Those roots are why prairie soil was so deep and black, and why the plant is now studied as a way to put carbon back in the ground.
Planting
Full sun and almost any soil, from sand to wet clay.
Growing
Cut it down in early spring before new growth. Divide when the center thins.
Harvest and use
Winter cover that stands up to snow, seed for birds, and an airy screen from July on.
What to watch for
Some varieties flop in rich soil. It seeds around a little.
