Virtues: A good ornamental grass for a backdrop or a tight space, because it is tall and narrow. Adds great fall and winter interest with its bright off-season foliage and fluffy seed heads. Does not bend or collapse in rough winter weather. Very adaptable and tolerant of various growing conditions.
Common name: 'Northwind' switchgrass
Botanical name:Panicum virgatum 'Northwind'
Foliage: Each grassy blade can be five feet long and about two inches wide. Olive green to steel blue during the growing season. Turns yellow in fall. Very sturdy, staying upright through even severe rain, snow and wind.

Origin: Roy Diblik of Northwind Perennial Farm (Burlington, Wisc.) selected this cultivar of switchgrass. The species is native to roughly the eastern two-thirds of North America.
Cultivation: Grow in full sun to part shade, in any soil. Prefers full sun and moist soils, but will also tolerate dry soils and drought, or wet soils. Do not fertilize. Cut back to about six inches tall in early spring. Spreads by rhizomes (underground stems) but is not considered invasive or aggressive. USDA Zones 2–9.
