Abstract
A new and distinct plant of ornamental Switch Grass named Panicum ‘Niagara Falls’ with wide, blue-green, broadly-arching foliage that retains its coloration into the fall. The upright and dense culms produce medium-height plants with broadly-spreading airy panicles beginning greyed reddish-purple and becoming tan seed heads that are retained into winter. The broadly-arching foliage produces a wide skirt effect below the panicles. The new plant is useful in the landscape as a specimen, en masse, or in a container.
