This year I'm growing some pole beans, seed bought at a farmer's market high in the Andes in Ecuador, received these in trade earlier this year. The seed was 10 years old but I did get a good many of them to germinate. I have no idea what kind they are but about half of them are flowering and producing beans, so at least these ones are not daylight sensitive. There was several different patterned seed coats in the mix and being old seed you couldn't tell what color they really were but I have harvested a few dried pods and the seed coats are mostly purple with swirls of a lighter shade.
They're about the size of pinto beans, definitely not a snap bean, I picked and steamed one, the pod was as tough as shoe leather but the tiny immature bean inside was tender and sweet, I should try another as a shelly. Most likely these are used as a dry bean. Any how it's been an interesting experiment.
The ones that haven't flowered, their seed coats looked slightly different, I was hoping they would have started flowering by now but it looks like the ones planted out in the garden aren't going to, possibly day length sensitive. I do have a couple of plants in the greenhouse but I'm battling spider mite, I keep spraying with safer's and they seem to be hanging in, so maybe these will produce something when the days get shorter.
