What kind of plants dominated the landscape of central North?

The landscape of central North America was predominantly characterized by vast grasslands and prairies, featuring grasses such as bluestem and switchgrass. These areas were interspersed with wildflowers and occasional woody plants like shrubs and trees near water sources. In more arid regions, drought-resistant plants like sagebrush also played a significant role in the ecosystem. Overall, the flora was adapted to the region's varied climate and soil conditions.
