Hidabeni Japanese Red Turnip Seeds – Brassica rapa

Scarlet-Skinned Japanese Turnips with Mild White Flesh

Hidabeni turnip (Brassica rapa) produces flattened, rounded roots with scarlet skin and mild white flesh. Harvested young, the roots bring crisp texture and a bright splash of color to salads and pickles, while the tender green tops offer another kitchen harvest.

Traditionally associated with the Hida region of Gifu, Japan, Hidabeni is a cool-season vegetable grown for its roots and greens. Pull a few young roots for a fresh meal and leave others to size up, checking regularly so they stay tender rather than becoming oversized.

Available Seed Packs

• 30 seeds
• 100 seeds
• 500 seeds
• 2,000 seeds
• 1 oz pack

The existing estimate is approximately 9,500 seeds per ounce. Weight-based seed counts vary by lot and are not exact guarantees. This listing is for planting seeds, not harvested turnips or live transplants.

Crop Details

• Variety: Hidabeni Japanese red turnip.
• Botanical name: Brassica rapa.
• Root: Flattened semi-globe shape with scarlet skin and white flesh.
• Flavor: Mild when harvested young and grown with consistent moisture.
• Growing season: Cool weather, generally spring or late summer into fall.
• Approximate maturity: About 50 days from sowing under suitable conditions; weather and harvest size affect timing.
• Harvest: Roots and tender young greens.

When to Sow

Direct sow in spring when the ground is workable and conditions favor steady cool-season growth. For a fall crop, sow in late summer or early fall, allowing enough growing time before severe cold. Winter harvest is climate-dependent, not guaranteed.

Avoid planning the main root crop for prolonged summer heat, which can reduce eating quality. Sow small batches about two weeks apart while conditions remain suitable rather than planting the entire supply at once.

Direct-Sowing Instructions

• Choose a sunny site with fertile, well-drained soil.
• Loosen the seedbed and remove stones and large clods around the developing root zone.
• Sow approximately 1/4–1/2 inch deep, cover gently and water with a fine spray.
• Keep the seed zone evenly moist during germination and early growth.
• Thin seedlings to approximately 4–6 inches apart for roots. Crowded plants may produce more leaves and smaller roots.
• Leave enough room between rows for weeding and harvesting.

Sow where plants will mature whenever practical, avoiding unnecessary disturbance to the developing roots.

Watering and Feeding

Maintain even soil moisture for steady growth and tender roots. Avoid repeated cycles of severe drying followed by heavy watering, and do not leave the bed saturated. Weed carefully while seedlings are small so they do not have to compete for light and water.

Prepare the soil with finished compost as appropriate and use soil-test recommendations for additional fertilizer. Avoid excessive nitrogen, which can encourage leafy growth at the expense of roots. Check young brassica plants regularly for pest damage and protect seedlings as needed with a suitable crop cover.

Growing in Containers

Use a large pot or trough with drainage holes and a loose, good-quality vegetable potting mix. A container around 16 inches wide provides room for a small crop; choose enough depth for root development rather than a shallow decorative tray.

Sow directly into the container and thin to about 4 inches apart for smaller roots, giving larger roots more room. Check moisture frequently because pots dry faster than beds. Water thoroughly when needed and allow excess water to drain. Grow fewer well-spaced plants rather than crowding the pot.

Harvesting Roots and Greens

Begin checking roots near the expected maturity date and harvest young for the mildest flavor and best texture. The earlier listing recommends harvesting around 3 inches in diameter; smaller roots can also be taken for tender eating. Do not wait for every root to reach an identical size.

Loosen the soil before lifting if needed. Take only a few outer leaves from plants you want to keep growing for roots; heavy leaf removal can reduce root growth. Tender thinnings can provide an early greens harvest.

Kitchen Uses and Storage

Wash roots and greens thoroughly. Slice young roots for salads, pickle them, or add them to soups, stews and curries. Tender tops can be sautéed or cooked with other greens.

Remove leafy tops after harvest and refrigerate roots and greens separately. Use the greens promptly for best quality. Store unused planting seed in a cool, dry place, and do not use planting seed as food or sprouting seed.
