Hairy finger grass, scientifically known as Digitaria sanguinalis, is a perennial grass native to Europe, Asia, and Africa. It belongs to the Poaceae family and is widely recognized for its distinctive appearance and growth habits.
Typically found in disturbed areas, such as lawns, gardens, and roadsides, hairy finger grass possesses an extensive fibrous root system that allows it to thrive in a variety of soil conditions. The plant derives its name from the characteristic, densely hairy texture of its seed heads, resembling fingers extending from a hand.
Hairy finger grass typically grows in compact tufts or spreading mats, with erect stems reaching heights of about 30 to 120 centimeters. The stems are hollow, slender, and can branch, allowing the plant to form dense clusters. The leaves are flat and narrow, measuring around 5 to 15 centimeters in length.
One of the notable features of hairy finger grass is its ability to produce large quantities of seeds, which are dispersed by wind or through attachment to animals and objects. The seed heads are composed of spikes or racemes, with each spike containing numerous tiny, oval-shaped seeds.
Considered a weedy grass species, hairy finger grass is often seen as a nuisance due to its invasive growth and ability to outcompete desirable plants. It can quickly invade cultivated areas and lawns, inhibiting the growth of other vegetation. Despite its invasive nature, hairy finger grass can be managed through regular mowing, hand weeding, and the use of herbicides.
