I've been told that 'switchgrass', when mature (takes a few years to get to 3-6' tall), makes great cover for deer and turkey, etc. Anyone have any experience with it? How is it for wildlife? For cover?

Apparently, it is a prairie grass that is native to numerous parts of the country including the eastern part of the US. It also is known as wobsqua grass, lowland switchgrass, blackbent, tall prairiegrass, wild redtop, and thatchgrass.
