I plant YB sweet clover every now and then. It is a biannual. That probably won't be a problem for you but here in ND I have issues with pulling it through the winter to get it in the second year. If I can establish a good stand and get it into the second year it will yield like crazy. I have not had the experience of others that have posted as far as palatability. My cows love the stuff. They will choose it over nearly anything else. The one caution is the chemical produced if it gets moldy. I think its call coumarin or something like that. When the clover gets moldy this chemical is produced. It causes the blood to be thinned in the cows and in severe cases the cows will bleed internally and abort, die, etc. I have never had this issue but I don't feed clover heavy either. I try to feed a bale here and there and like I said, no problems. I've heard a shot of vitamin K will combat the blood-thinning effect.
