The Purple Yard Long green bean is an Heirloom garden seed that dates back a few thousand years. This is Non-GMO and unchanged. These will grow best in hotter areas, and will also need a trellis of some sort. They will grow 2 to 3 feet, hence the name Yard Long, and will stay tender. To our farmers market friends, this variety will be a hit. You can't get these seeds just anywhere, and you certainly won't get these beans at the corner supermarket. Will make a very nice addition to your vegetable garden! Happy growing!!!
