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. This grass is an invasive species considered an aggressive weed in certain countries, including China, Mexico and the United States.
Together with Portulaca oleracea, Ipomoea pes-caprae and Melanthera biflora, Digitaria ciliaris is usually one of the first species colonizing degraded or altered environments in tropical zones of the planet.
This grass is as annual 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 5-10cm long sub-digitate racemes.
