Panicum virgatum cultivars
Switchgrass is native throughout North America and is a dominant species of the tallgrass
prairies. It doesn’t mind most soils and actually grows well in wet and dry locations.
Full sun is the best exposure for switchgrass, but it will grow in part shade; too
much shade or rich soils may result in floppy plants. Switchgrass is a warm-season
perennial, growing largely as a bunchgrass 3 to 6 feet tall, but may spread by rhizomes
or self-seeding. Switchgrass has an upright, stiff form overall. Flower panicles are
open, lacy sprays, with a purplish tint that persist into the winter. Leaf color is
generally medium green turning yellow, sometimes with orange tints, in fall; however,
several cultivars exist – ‘Heavy Metal’, has metallic-blue foliage, ‘Northwind’ is
bluish-green, ‘Shenandoah’ has foliage with dark purple tips, and ‘Cheyenne Sky’ turns
wine red. Winter color is tan to beige. Once established, switchgrass is very drought
tolerant. It is grown as an accent, in groups or masses and can be effective as a
screen. It also works well in native plant gardens, wild gardens, meadows, naturalized
areas, as well as rain, water, and bog gardens.
