Switchgrass (Panicum virgatum 'Heavy Metal') stands strong all winter long. I love the sound it makes when the wind rustles through the leaves. Switchgrass is a warm-season grass, which means most years I don't think it really gets started in Middle Tennessee until April. Typically, I'd probably wait until late March to cut back the switchgrass. Since March has been an unusually warm this year, I cut back the switchgrass about a week ago. Now I can't tell which way the wind is blowing anymore just by looking out the window to see how the grass is leaning.
