The Tokyo Long White Onion, an heirloom variety originating from Asia, is prized for its lengthy, slender green tops, which can grow up to 41 centimeters tall. Unlike some onions, it doesn't form round bulbs but maintains a consistent cylindrical shape from top to root.

This versatile onion is easy to cultivate and thrives even in containers, making it a convenient addition to any garden. Its fresh, mild flavor enhances a variety of dishes, including soups, salads, and stir-fries.

Characterized by striking white stalks and vibrant green leaves, this Japanese heirloom adds both visual appeal and delicious taste to culinary creations. With a flavor akin to leeks, it's commonly used as a bunching onion and typically matures for harvesting in around 80 days.

Known by various names across different regions, such as spring onions, Japanese onions, or scallions, Tokyo Long White onions are a staple in Eastern Asian cuisine. Their sweetness makes them a popular choice for enhancing the flavor of soups, stir-fries, salads, and traditional Asian dishes alike.

How To Grow

Sowing: Since onions take a few months to mature from seed, gardeners with a short growing season may want to start their Tokyo Long White bunching onion seed indoors. Plant the organic onion seeds approximately 1.3 centimeters deep in a flat 5-8 centimeters before the last frost date; keep the soil moist and at approximately 20 degrees Celsius. When the tops begin to flop over, cut them off to approximately 8 centimeters to focus the growing on the roots. Four weeks before the last frost or when the soil reaches at least 10 degrees Celsius, transplant the seedlings in rows 30.5 centimeters apart. For direct sowing, sow three seeds per 2.54 centimeters approximately 1.3 centimeters deep in light, rich soil and full sun. Thin the seedlings 5.1-15.2 centimeters apart, depending on the desired size. Thinned onions can be transplanted or used for fresh eating. For companion planting benefits, plant organic onion seeds with members of the cabbage family, lettuce, or tomatoes; avoid planting onions with peas or beans. In areas with warmer winters, onions may be grown as a fall or winter crop.

Growing: Onions need moisture especially in their first several weeks of growth, and they cannot fight against weeds; mulching onions can help with both moisture and weed control.

Harvesting

Tokyo Long White bunching onions can be harvested as early as 70 days after planting, with their flavor intensifying the longer they're left in the soil. While suitable for both green onions and scallions, they don't retain their quality for extended periods and are best used fresh.

Seed Saving

Onions require a period of overwintering before they can produce seeds. In regions with milder climates, simply layering a thick mulch over them and removing it in early spring is sufficient. However, in areas experiencing very cold winters, it's advisable to pull up the onions, trim half of the stems, and store them in a dry location at temperatures between 32 to 40 degrees Fahrenheit until the arrival of spring, when they can be replanted.

Prior to planting, make a small X-shaped incision at the top of the onion to facilitate the emergence of the stalk. As the plants grow, they will eventually flower and develop seeds. Carefully remove the seed heads once the seeds are visible, ensuring not to inadvertently disperse the seeds. Spread the seed heads in a well-ventilated, dry area and allow them to dry for several weeks. Afterwards, separate the seeds from the heads and store them in a cool, dry place for up to two years.
