I have had good luck with winter rye. I have a good plot of clover and try several other things when the weather is favorable. When the bed is ready for fall but the rain doesn't come, winter rye has saved the day several times. It germinates and grows fast. It grows at lower temperatures then most other stuff and frost don't bother it. Deer and elk love it. Just make sure its cereal rye and not rye grass.
