Kiva Bean

I got seed for this 'Kiva' bean at a seed exchange and don't know the history. The pods are very slender, light green and stringless at 5 inches in length. The mature beans are quite striking and are marked a bit like a Shield Figure bean. The plant has a bush habit and is productive. What variety this may be is a mystery to me and I've grown a lot of beans over the years. They did well here in the cooler weather this last spring and matured in about 60 days. I can put about 60 seeds in a packet

Recall that international shipping of bean seed requires additional postage.
