Panicum virgatum 'Northwind' has been named the 2014 Perennial Plant of the Year. The ornamental grass was also featured in Garden Center's roundup of readers' favorite grasses, which was published in the February 2014 issue. Roy Diblik selected ‘Northwind’ from a population of Panicum virgatum he raised using wild-collected seed from plants growing along railroad tracks in South Elgin, Ill. In July 1983, he noticed that one plant had wider leaves and a very upright growth habit, unlike the typical arching form of the others. He gradually built up stock of the upright one. In 1992, when Northwind Perennial Farm opened, he introduced it and named it ‘Northwind.’
‘Northwind’ spreads slowly to form erect clumps of slender, steel-blue leaves about five feet tall. In late summer, the foliage is topped by a haze of showy, finely-textured flower panicles that rise to 6 or 7 feet, and that open golden yellow and mature to beige.
Deep roots make ‘Northwind’ remarkably drought-tolerant, once established. Like most ornamental grasses, Panicum virgatum ‘Northwind’ is seldom eaten by deer.
