An impressive heirloom pole bean that has no trouble climbing to the top of massive cornstalks like my Hopi Blue that reaches 7-9 feet tall, Iroquois Skunk Beans are edible both in the green stage as fresh beans, with unsurpassed old fashioned flavor, and also excellent dry beans that you can thresh and store to have throughout the winter, spring, and til your next season comes!
These beans will be measured by weight for packing, but for convenience I also quote the approximate count. If you are growing Three Sisters style, you can vary quite a bit in how many beans you sow- you can have beans with every corn hill, or every other, etc, and you can vary from 1-3 beans per corn hill. For a self-sustaining plot of at least 400-500 corn plants, and an average of 2 beans every other hill, you'd need about 70 plants. Assuming you fend off the deer and your own raging temptation to eat them all as green beans, you should assume a pole bean will yield 20 times its planting weight- you might get 2 lbs of beans almost "for free" from a cornplot capable of 100-150 lbs, and an untold number of squash.
