Are those varieties winter hardy here in central Missouri? I grow hybrid pearl millet every year but it goes south at the first killing frost. Early last fall, I worked up a 4 acre pasture and tossed in a 5 pound bag of Austrian Winter Peas into the seed/fertilizer mixture. Just to see how they would do. I found several of them sprouted later on and doing well. Of course you aren't going to see them often at that seeding rate. When I walked the pasture a few weeks ago, I didn't notice any of them. In all fairness though, there was a notorious "Sheep Break" which should have made the national news. It seems that the sheep managed to make it through the poor excuse of a section of fence, to call the fence a good bluff would be quite the exaggeration. At any rate, I have no Austrian Peas anymore, and my new pasture is quite short now.
EDIT: Duh. I confused the winter oats with another post I saw earlier about Tiff millet. Sorry
