Digitaria sanguinalis is an annual grass (living for 1 season only) with long (up to 1m) sprawling stems. As with all grasses it has ďŹ brous roots. The many soft stems grow close to the ground in an open space or will push up through other grasses when crowded. The stems when they are close to the ground will often produce roots at the nodes (elbows along the stems). Stems are variable in colour from green to purple, as are the ligules. Ligules are the small appendage seen at the base of the leaf when the leaf is pulled back from the stem. The ligule on this grass is a membrane 1-2mm long.

In drought situations with penetrable soil, the root system can grow to over 2 m deep, though most of the root mass is less than 60 cm under the surface. The grass creeps along the ground and root wherever a node touches the ground, forming a dense mat. Bermuda Grass reproduces through seeds, through runners and rhizomes.
