In S.E. Africa, plants are hexaploids. Thrives in sheltered and disturbed areas, neglected areas near crop fields, and in grass fields where it tends to be a grass weed. Adapted to tropical and subtropical summer rainfall areas. Quite drought-resistant, and tolerates seasonal burning. Cultivation Propagated by seed.
Plants are good seed producers but show great variability in their ability to germinate.
Usually the very light seeds are spread by wind, allowing invasion of new areas. Due to glume removal, the embryo becomes exposed directly to light and moisture, causing higher germination. Also increased depth of planting of seed lowers the germination percentage. Periodic tillering from the underground rhizome maintains the perennial habit of this grass. Forms open turf under grazing.
