Overview
Japanese Long is an Asian heirloom of the kyuri type that anchors Japanese cooking: slender fruits 8 to 12 inches long and 1 to 1.5 inches thick, smooth dark green skin so thin it needs no peeling, a tiny seed cavity, dense crisp flesh and a mild, sweet flavor with almost no bitterness. That density keeps slices crunchy in salted tsukemono and oi sobagi kimchi as well as in fresh salads. Grow it vertically; direct sow 1 inch deep after frost once soil tops 65 F and train the climbing vines on a trellis for straighter fruit and better airflow. About 68 days.
