rye grain, like wtnhunt suggested, is a good choice. I've had good luck with red clover in remote low sunlight areas. I'll take a rake and clean as much of the debris off the ground and kind of scratch up the surface--then broadcast it right after or even better during a good rain or on muddy ground when more rain is expected. The rain will help cover the seed giving better germination. You won't have much luck if you just toss the seed on dead leaves and branches.
best of luck with your plot
