Diarrhena americanaAlso known as:
Diarina festucoides, Korycarpus arundinaceus
Diarrhena americana is an ornamental grass with 3/4" wide, dark green arching leaves. It forms open clumps up to 3' tall. The grassy tufts will turn golden brown in fall and persist through winter. It produces attractive seed heads atop slender stems that will tend downwards under the weight. The seeds are 1/4" long or more, oval with a distinctive beak at the end which gave rise to the common name "American beakgrain".
Diarrhena americana is a low maintenance, non-aggressive grass that is adapted to shaded conditions. It is easy to grow in average to rich soils. It prefers a moist environment but can tolerate dry shade, and is also often found naturalized along wet stream banks. It spreads both by seed and by creeping rhizomes, slowly forming dense colonies under ideal conditions. A good choice for a shade garden specimen, or woodland groundcover. Flowering times are in June and July. Zones 5-6
Easy to propagate from seed or by clump division.
American beakgrain is a rare species and should be considered threatened in its natural range. One of the few grasses adapted to full shade and with good ornamental value.
