About

Diarrhena americana, also known as American beak grass or American beakgrain, is a native, perennial bunchgrass of North America.

Historically, Diarrhena americana was the only species of beak grass recognized in the United States; however studies have suggested that the known beak grass is to be classified into two distinct species, Diarrhena americana and Diarrhena obovata.

How to grow it

Diarrhena americana is cultivated as an ornamental grass, grown in traditional and wildlife gardens, and in natural landscaping projects.

It is considered an easy plant to grow and maintain, not needing much sun or water while generally being a tough plant. It will tolerate drought, heavy shade, competition from eastern black walnuts, and urban air pollution. When available, the plant will grow into dense clumps in moist rich soils in full shade.

Where it grows

Diarrhena americana naturally occurs throughout the Midwestern United States, including in eastern Oklahoma and Missouri; south to Alabama; east to Kentucky, the Appalachian Mountains and northern Maryland; and north to southern Illinois, Indiana, Ohio, and southern Michigan.
