To add to what's been listed so far, try to get some Durana clover also. It's a new variety of ladino and seems to grow well. It handles heavy grazing better and from what I've seen it will also compete with weeds better than ladino. I've got one of my plots sewn with the Durana and I'm impressed so far.

I prefer to keep the different varieties planted in seperate locations. This way I can tell which the deer prefer and which grow better in my area. Then when I figure out which types did the best I can combine them into a mixture.
