Our plots in south MS are in full bloom with crimson clover (and wheat and oats going to seed). Deer havent touched them in 3 weeks, as our native browse of greenbrier, blackberry, and wild grape are fully leaved out. That's fine, as the plots are a haven for insects and the birds and reptiles attracted to them. I shared a comfortable spot next to a fence lizard at the edge of one of our plots turkey hunting this afternoon, and a bobwhite was sitting on a nest in the plot not 10 yards away.
Crimson clover has SO many benefits to wildlife besides whitetail as well as soil quality, that it's (or another annual clover variant) is always worth planting.
