Grasses are the dominant species in North American prairies and switchgrass was one of the dominant grasses. This aggressive grass tends to dominate other prairie species in smaller sites and may form thick stands. It is, however, one of the characteristic grasses of tallgrass and wet prairies, but may also grow in dry prairies. It grows three to five feet tall, and looks rather delicate.
