66 days. Allium cepa. Open Pollinated. The plant produces very flavorful bunching onions. These salad onions have long white stalks. Most of the plants can be eaten with little waste. Great for sukiyaki, soups, and salads. Excellent for spring or late summer harvests. This improved version of the Ishikura Onion has long-distance shipping qualities. These green onions do not form bulbs and do not multiply by division. The stalks can be harvested when pencil-thin or left to grow as thick as a mature carrot. It is tolerant to warm and cool temperatures and is suitable for winter harvesting in some areas. One of the most popular bunching onions in Japan. An excellent choice for home gardens, farmer’s markets, and market growers.
