Plant Spotlight: Red Switch Grass
Also called tall panic grass, tall prairiegrass, wild redtop, and thatchgrass, red switch grass (Panicum virgatum) is a stunning, native ornamental grass. It grows 2-5 feet tall depending on variety, and tends to have a dense, columnar form, with stiff round stems, making it a great option for building visual screens, or as a tall backdrop against flowering perennials in a garden bed.
Red switch grass is celebrated by gardeners for its vibrant foliage and year-round interest. Emerging blue-green in spring and transitioning into a dramatic wine-red by late summer, the show culminates in a brilliant burgundy color in fall. Even throughout winter the stems remain upright, turning beige with the cold.
Red switch grass is so versatile it can be found in remnant prairies, in pastures, along roadsides in many areas, and even in brackish marshes. It thrives in full sun and will tolerate partial shade, although it may flop if it’s not getting enough sun. Make sure it has well-draining soil, and keep it moist until the plant is established, and you should be good to go!
Red switch grass is just one of the perennial grasses we’ve got in stock here at The Wedge, so swing by even if it doesn’t fit your bill. We’re excited to help you grow it better!
