Panicum virgatum 'Shenandoah' is an ornamental grass with a compact, clumping habit. The key characteristics that differentiate it from the parent species, are its short stature, which at about 3' is likely the shortes and most compact P. virgatum cultivar. Also, and more notably its blue-green foliage develops fall colors of burgundy and purple as early as late June, which is much earlier than even other cultivars. It is thought that his color shift accounts for the plant's compact habit, because the lack of chlorophyll so early in the season likely stunts the plant's growth
As with the straight species, 'Shenandoah' is adaptable to a wide range of soil types, and moisture levels ranging from wet to dry. It is best grown under full some, but it will tolerate some shade.
Many people involved in horticulture and garden design, believe that 'Shenandoah' will likely become the most popular of all Panicum virgatum cultivars. It was discovered by Hans Simon in Germany from a seedling of Panicum virgatum ‘Hänse Herms’, and assigned the variety name in 1990.
