This is an heirloom variety of Straight Eight with many decades of service (i.e., since 1935). The seed packet recommends sowing 2 seeds every 12" and setting the rows 36" apart. It is helpful to me to read that a single packet will sow up to 22 feet of trellised cucumbers. This will be a school project. Surely the children will be fascinated by the growing habit of this vegetable and will enjoy eating the cucumbers even more!
