I recommend you mix your own. You can't beat this mix in my opinion.
50 lbs oats or wheat
15 lbs crimson clover
5 lbs arrowleaf clover
5 lbs dwarf essex rape
This will cover a 1 acre plot size.
This is a annual plot,. not a perrenial. For a perrenial plot i recommend
50 lbs oats or wheat (nurse crop)
7 lbs red clover
5 lbs white clover
1 lb chicory
2 lbs dwarf essex rape ( winter food source)
If you just simply don't care a thing about mixing yourself ,.. i recommend
Imperial pure attraction for a annual plot
Pennington durana clover with tecomate chicory for a perennial. I would still use the oats or wheat for a nurse crop!!
