Panicum virgatum Northwind Grasses (Switchgrass) is a striking architectural plant. These super grasses produce dense, upright clumps with narrow, straight, strong upright leaves that range from olive-green to dark-green. In late Summer, the leaves are topped by golden flower spires, which appear to hover cloud-like over the flowers. As the year goes on, both foliage and flowers turn to a golden brown. This makes for stunning ornamental displays in Autumn as well as providing shelter for birds.
