According to historical records, the Romans were the first to grow cucumbers in greenhouses. The goal was to provide cucumbers for Emperor Tiberius throughout the year on the Isle of Capri. In time those long cucumbers were grown throughout Europe. The fruits reach up to 14 inches in length, and are sweet and crisp. They are also completely bitter free and burpless. As with any large cucumber, you will want to trellis them if you want them to be straight. 68 days.
