yard long green beans: heirloom garden seed.. . These wonderful green beans are non gmo and have been around for a few hundred years the beans are 2 to 3 feet and you grow the same as you would any pole bean. These are the same as our other yard long but these are all green. The yard long is not cold hardy. And needs to be planted in the spring but in hotter climates can be planted just about anytime. To our farmers market friends you will have them lined up for These. Happy growing!!!
