What snipe said it depends on what you are looking for in a finished product, as you indicated you are not mowing it, I planted a cover of annual rye grass and wheat for a quick hold for the dirt to avoid erosion, and then interseeded that with a clover mix that lasted for a couple yrs and made some really great deer and turkey attractant for a couple yrs , also mixed some crown vetch seed in which I really like for long term, it is a erosion control vegetation that I think is pleasant to look at, has nice flowers, spreads semi slowly but thoroughly, and will pretty much take over the area in a couple yrs, and best of all will grow in really poor dirt.

After several yrs the clover is sorta thinning out and the vetch is taking over. google it and see what you think of the looks of it. its not extremely beneficial for wildlife but it is pleasant to walk thru and does extremely well to stop all erosion. bees like the flowers tho.
