[4] It is widespread in the Western Hemisphere, native from the eastern United States to northern South America.

[8] Eastern gamagrass can survive droughts and floods for a long time because of its rigid and thick rhizomatous roots which firmly holding the plant upright.

Tripsacum dactyloides is widely spread throughout the United States, from Connecticut to Nebraska and south to Florida and Texas.

Moreover, moist, nonalkaline lowland areas will maintain the growth of gamagrass because the land can endure a longer time under flood conditions.

The deep roots, which extend to around 4.5 m (15 ft) underground, are the key structure that allows gamagrass to tolerate drought.

[7] Eastern gamagrass was widely considered a high class feedcrop among the early settlers of the United States.

Around the late 1980s and early 1990s, people started to pay attention again to eastern gamagrass as a forage in summer, since it is productive, palatable and easily digestible by almost all cattle.

For these reasons, gamagrass is ideally suitable for feed crops, including hay and pasture forage for which rotation of grazing seasons is controlled.

[7] Eastern gamagrass requires a moderate amount of carbohydrates stored in the leaf bases for regrowth.

For example, the empty space in the middle of bundles is large enough for wild animals like quails and prairie chickens to build nests.

meridionale is mentioned to be a subspecies most common in South America, having a morphological difference with its North American counterpart in that it has 'subdigitate recemes usually appressed with the apical male sections typically curved'.
