[3] It is a sturdy, hardy, persistent, aggressive grass that easily outcompetes many other plants and becomes the dominant species in disturbed habitat types, such as overgrazed fields.

[1] The inflorescence is a wide cluster of branches bearing green leaflike spikelets with darker bases that contain bulbils.

Viable seed is rarely produced, and the plant usually reproduces asexually via its basal bulbous sections and via bulbils.

[2] Although the plant reproduces vegetatively (asexually) most of the time, it has been shown to possess high genetic variability.

[1][dubious – discuss] Many types of animals, including wild and domesticated ruminants, small mammals, and birds, readily consume this grass, especially the bulbils in the inflorescences, which contain some starches and fats.
