Delar small burnette is another planting that you could mix with chicory, if your wanting a perrenial plot. I've found no planting as persistent as small burnette. Deer like it and it is extremely drought tolerant. For any clover to do well, you have to have soil that will hold moisture during the dry days of summer and early fall. As crimson said, shade is your friend with perrenial clovers. I would try and build my soil, before trying any perrenial plantings.
