Let's see here, the two named varieties...
Torkuviahe Pea - from West Africa, picure:
Copied text from website: "An old variety grown by the Ewe people of West Africa. As far as we know only a few farmers in the Lake Volta region are still growing it. Beautiful small red beans are borne in long straight pale-yellow pods. Traditionally cooked in stews or simply cooked with rice and served with any spicy fish, meat or vegetable sauce on top. Can also be eaten like string beans when young and tender.
Grey Speckled Palapye - crowder type (Baker Creek was having a half-off sale

). Read in the comment section that it is a bush variety and grows more like a soybean. Picture:
Copied text: "Flavorful, gray-speckled peas in large pods; very early and perfect for the North. From a market in Palapye, Botswana. Rare."
The other two are completely unamed varieties that come from a freind in New York. He picked the peas from a bage of mixed beans that he got from Chinatown and grew them out, the bag was originally from Thailand. One is small, white, and wrinkly with a brown eye. The other one is just large and black (about the size of a pinto bean)with the occasional brown spot.
I've read from a few places that southern peas/ cowpeas need support. I was just thinking that it would awfully nice not to worry about staking them, I'm going to need all of my stakes for the tomatoes and pole beans. I don't see the peas growing up poles when I see a picture of a field of them.
