Chloris gayana (Rhodes grass).
Chloris gayana is a robust, strongly stoloniferous grass native to Africa that has been extensively introduced as forage across tropical and subtropical regions. Traits such as its ability to grow in a wide range of environmental conditions, its drought-resistance and its ability to rapidly reproduce both by seeds and vegetatively have facilitated its escape from cultivation and subsequent naturalization. Once established, C. gayana often grows to form almost pure stands that smother native species. Currently, this species is regarded as an invasive in Australia, Spain, Argentina, Paraguay, Mexico, Costa Rica, Cuba, Anguilla, New Caledonia, New Zealand and Hawaii. It is also included in the Global Compendium of Weeds.
