Andropogon virginicus has also been introduced to Japan and Australia.
It competes with other species by allelopathy, releasing persistent herbicidal chemicals from its dying tissues, such as decaying leaves.
A. virginicus colonizes disturbed areas such as abandoned mining sites.
It is a weed of pastures and grazing ranges, where it proves less palatable and nutritious to cattle than other grasses.
This species is tolerant of fire and grows back quickly and more abundantly after a burn.
It is perhaps most problematic in Hawaii, where its natural growth patterns are out of synch with the local climate.
It is dormant during the Hawaiian rainy season, dying back and leaving the slopes it has colonized exposed and vulnerable to significant erosion.
Despite its weediness, the grass is sometimes grown as an ornamental plant.
