Finger grass is a common term used to refer to several species of grasses belonging to the genus Digitaria. These grasses are recognized by their characteristic finger-like seed heads, which inspired their common name. Finger grasses are annual or perennial plants that typically have wiry stems and can grow up to 3 feet in height.
One widely known species is Digitaria sanguinalis, also known as large crabgrass or hairy finger grass. It is a common weed found in lawns and gardens, known for its quick growth and ability to withstand drought and foot traffic. Large crabgrass has flattened leaf blades and can spread rapidly through numerous seeds produced by its finger-like seed heads.
Finger grasses are adaptable and can thrive in various soil types and climates, making them widespread and persistent weeds. They can be found in North America, Europe, Asia, and other regions around the world.
In addition to their invasive nature, finger grasses also have some beneficial qualities. They are often used as forage for livestock due to their high nutritional value. Some species, like Digitaria eriantha, are cultivated as pasture grasses because they are highly drought-tolerant and provide valuable forage during dry periods.
Overall, finger grass refers to a group of grasses with finger-like seed heads, which may include both nuisance weeds and valuable forage plants.
The etymology of the term "finger grass" arises from its appearance, specifically the similarity of the grass's seed heads to fingers. The name "finger grass" is a descriptive compound noun, with "finger" referring to the long, thin, and slightly curved shape of the seed heads, resembling fingers on a hand.
