American Beakgrain (Diarrhena americana) Diarrhena ah-mer-ih-KAY-nah

Diarrhena americana, commonly known as American beakgrass, is an attractive, clump-forming grass native to the eastern and central regions of North America. This perennial grass forms a neat, upright tuft of slender, green leaf blades that typically reach 12-24 inches in height. In late summer, Diarrhena americana produces airy, terminal panicles of delicate, greenish-white flowers that rise above the foliage, adding visual interest. As the blooms mature, they develop a distinctive, beak-like seed head that gives the plant its common name.

American beakgrass prefers partial shade to full sun and well-drained, average to dry soils. It is an excellent choice for natural, woodland-style gardens, where its clumping habit and fine texture contrast beautifully with the coarser leaves of surrounding perennials and shrubs. Diarrhena americana also works well when used as a groundcover or border plant, creating a tidy, low-growing swath of foliage. The grass's tolerance for drought and poor soil conditions makes it a low-maintenance addition to mixed beds, rain gardens, and other challenging landscape settings. With its unique seedheads and cool-season green foliage, Diarrhena americana provides season-long interest and a touch of native charm to a variety of landscape designs.
