Distribution
Digitaria ciliaris is a tough plant, believed to have originated in Asia but now found all over the tropical belt of the planet, as well as in many temperate regions of both hemispheres.[5] This grass is an invasive species considered an aggressive weed in certain countries, including China, Mexico and the United States.[5]
Together with Portulaca oleracea, Ipomoea pes-caprae and Wollastonia biflora, Digitaria ciliaris is usually one of the first species colonizing degraded or altered environments in tropical zones of the planet.[6]

Description
This grass is an annual plant that can grow up to 1 m tall but is usually much shorter. The roots are at the nodes and the stems produce runners that allow the plant to grow fast forming scruffy-looking patches about 1 m across and half a metre in height. The leaves are linear to linear-ovate narrowing at the tip to 15 centimeters long. The inflorescence is at the top of a long stem, usually much taller than the leaves, with two to nine 5–10 cm long sub-digitate racemes.[5]

Forage Crop
Southern crabgrass, and the related large crabgrass, especially the cultivars 'Red River Crabgrass', 'Impact', and 'Quick-n-Big', have been utilized as a forage crop for livestock, as it is a highly nutritious warm season grass.[7][8] Red river crabgrass responds well to nitrogen fertilizer, growing up to 3 feet tall, and needs to be in rotation with cool-season forage.
