Here's the description from the Southern Exposure Seed Exchange website (note that this variety is also called "Genuine Cornfield" and "Scotia"):
" 83 days. [Possibly of pre-Columbian origin, one of the oldest beans cultivated by the Iroquois who used it as a corn soup bean and bread bean. In the Cayuga Iroquois dialect its name means 'wampum bean.'] Shade tolerant, an old favorite for growing with corn. Straight 5-7 in. pods, gray-brown seeds with brown mottles and stripes. Best harvested before seeds fill the pods. Use for snap or green shell. Produces very well during high heat. A valuable variety for keeping the nitrogen in your corn patch. "
