Northwind switchgrass Panicum virgatum 'Northwind'

'Northwind' is a cultivar of the deciduous, native perennial, ornamental grass that is known as switch grass. This cultivar is dense, upright, compact, and columnar with a clumping habit. The leaves are olive-green to bluish-green. In the late summer, the flowers appear as pink and green spike-lets that are arranged in large branched panicles that form an "airy cloud."  The seed heads follow, and the foliage becomes yellowish-beige in the autumn.

'Northwind' was developed by Roy Diblik at the Northwind Perennial Farm in Lake Geneva Wisconsin. It was named the Perennial Plant Associations' Perennial Plant of the Year in 2014. 

The genus name, Panicum, is the old Latin word for millet. The specific epithet, virgatum, means "twiggy," 'Northwind' is one of the best vertical forms available of all the cultivars of this species.

This warm season grass thrives grown in full sun and will tolerate a wide range of soil types. It prefers average, medium to wet, well-drained soils of sand or clay.  Overly moist and rich soils should be avoided because it tends to cause the plant to flop. If planted in too much shade, it will also begin to lose its form. It is drought, deer, and wet soil tolerant. It spreads by creeping rhizomes. The foliage should be left standing during the winter months to help reduce soil erosion. The foliage also provides a food and wildlife habitat for pheasant, quail, turkeys, and other birds.  'Northwind' requires very little maintenance except to cut back the foliage in late winter or early spring. 

'Northwind' may be used as an accent or planted in groups or mass plantings. Consider using this cultivar in a native plant garden, wildflower garden, meadow, or naturalized area due to its multiple seasons of interest and lack of maintenance.
