Different plants are attractive to deer at different times of the year. This is the reason for planting multiple forages. What deer prefer in your area, has a lot to do with what they have to eat as far as browse and nearby ag. Deer with limited ag available, eat what they have to. Deer love clover of all types. I see them eating crimson,yucchi, and all white clovers. I believe they prefer white clover the most. Typically its higher in protein. If your planting clover and the deer are not eating it, then you need to take a look at your soil.
