Danthonia Grasses

Danthonia are in the grass family, Poaceae, and are commonly called the oat grasses. The group includes many species, some native to North America and others, such as Australian wallaby grass and Caribbean Danthonia domingenisis, found in regions around the world. The common forms of the grass found in the United States are California, poverty, timber, flattened and one-spike oat grasses. The grasses are perennial and carry tufted flower spikes with hairy sheaths.

  1. Danthonia Californica

    • Californica is a native grass that can grow from just under 12 inches to over 30 inches tall. The perennial grass has fibrous roots and open sheaths which may be hairy or smooth. The blades broaden from the base and are fringed with fine hairs. The inflorescence is made up of three to six spikelets with the seed pack shorter than the stem. Californica is found in moist or dry grassland, meadow, open woods, sandy or rocky shores or mountainous ranges.

    Danthonia Compressa

    • A species found only along the eastern states and Alaska, Danthonia compressa or flattened oat grass, is found in open and shady areas. It is not a truly native species, but was introduced and naturalized. The flowers may have six to17 spikelets and have foliage blades that are nearly 12 inches tall. The culms are flattened, earning the plant its name. This grass is also slightly furry with heavier hairs along the sheath. This grass is also called mountain oat grass

    Danthonia Spicata

    • Poverty oat grass is a native clumping grass with 5-inch-long basal leaves that are extremely slender. The entire clump becomes a curly mass of foliage, both young green growth and older, dry, brown, spent blades. These are almost hairless but there is slight furring at the sheaths. It is found in sandy to rocky soils in woodlands, prairies, limestone and sandstone glades, disturbed soils and over grazed meadows. The grass grows best in poor, dry soils where there is little competitive vegetation.

    Danthonia Intermedia

    • Commonly called timber oat grass, Danthonia intermedia is a species found in open forest areas and mixed grasslands. Unlike the majority of the Danthonia species, Timber oat grass is palatable to livestock and wild animals. The plant has basal meristems which allow it to re-sprout after heavy grazing. The grass is tufted and can grow 4 to 20 inches tall. This type of oatgrass has an inflorescence with four to nine spikelets. Danthonia intermedia has a shallow, fibrous root system which makes it ideal for minimizing erosion.
