The longest green beans you can grow, these are actually a member of the cowpea family. Many beans may actually grow a yard long! Beloved and widely eating in Asian cuisine. Plant these beans in the hottest, most humid spot in your yard or greenhouse in acid soil near 6.5 pH (if your soil is more alkaline than this, like mine, add 1 cup vinegar to a gallon of water to water these beans). These need hot soil to germinate and a trellis to keep the beans off the ground. I now offer these beans after one of my friends declared these are now the only beans she will grow, because of their flavor and volume of harvest! 80 days. Every seed we sell is 100% natural, chemical-free, heirloom, non-GMO. Pole habit means you can grow a lot of beans in a small space. 8 heirloom seeds. Free shipping on orders over $34.
