crown vetch is what i love. if enough water it comes back every year. i have it every wheres i dont want weeds, it chokes out the weeds and is good for deer and such. if your looking for a having to plant every year ground cover grow hairy vetch. it goes nuts and is nice to look at and the deer love it. has to be planted every spring. the county plants it in the ditches every spring around here. common vetch is like crown vetch, comes back every year. also plant duch white clover with anything you plant. it is lowgrowing but gets thick and comes back. any grazing animal go hard after it. minn. is full of it. i plant it with my lawn as it helps the grass really grow. doesnt cost a arm and a leg as the crown vetch and common vetch do. if your in good rain country broadcast sweet clover, yellow and white every rainy season. it come back every two years and gets 6 ft. tall and every animal that loves green things will go nuts on it. bees lover it the most of all. years ago i met a african student who was rich with thousands of acres of grass land in his family. i told him about white and yellow sweet clover and he bought sacks and sacks of the seed and sent it back to africa to broadcast in the rain season so his goats and cattle could get fat on it. in north dak with their rich soil the sweet clover gets so tall you cant see the cattle in it. horses love the stuff also. a field of brome grass and sweet clover makes the best hay for animals their ever was. dont forget field peas also. the kind for dried peas for soup. they make good hay also and very good deer feed. around here they plant wheat and rye together and may mix some hairy vetch in the mix and it makes the best hay ever. millet grow anywheres and is a crop for man and animal use you can depend on. it is the go to crop when all else fails. wild sun flowers around here really attract the deer. if you plant wild sunflowers mixed with hairy vetch and corn mixed in the spring you will have all the deer and elk you want in the fall. on the west of me is lots of corn and behind me is a section of winter wheat. my son wont be hunting deer far from the house in nov and dec. their will be more deer than we want on each of these crops.
