We are currently growing 14 different cultivars of little bluestem at the Minnesota Landscape Arboretum. One of the new forms is called Smoke Signal, with blue and red foliage in the summer and dark red foliage in the fall. Smoke Signal is 34-42 inches in height, and 25 inches wide…a nice size!
Along with Blue Heaven® the 45-55 inch tall Minnesota selection….these two cultivars are both upright, have good fall color and are the best of the 14 at the Arboretum for 2016. Many of the other cultivars have lodged or fallen over, have little or poor foliage color, or show little vigor.
