Watanabe Early Burdock (Gobo), Heirloom Seeds — The Home Garden-Friendly Japanese Gobo With Tender 12–16" Roots

Watanabe Early Burdock (Arctium lappa) is an early, light-skinned Japanese heirloom gobo bred for home gardens. Where Takinogawa produces roots up to 3 feet long, Watanabe Early produces crisp, tender roots just 12–16 inches — a manageable size for raised beds without sacrificing the rich, earthy flavor that makes gobo one of Japan’s most beloved vegetables. Non-GMO, heirloom, cool-season annual. 75–85 days. Important: Once established, burdock is persistent and difficult to remove — choose your planting location carefully.

In the Kitchen

• Kimpira Gobo: Shave burdock and julienne carrots; stir-fry in sesame oil with soy sauce, rice wine, sugar, and hot peppers — the definitive Japanese gobo dish
• Fresh salad: Shave thin and dress with sesame oil and citrus
• Tempura: Slice thin and fry in light tempura batter for a crisp, earthy bite
• Pickling: Slice and pickle in rice vinegar with sugar and salt
• Soups & stews: Add to miso soup, nabe, or braised dishes for depth and nutrition
• Prep tip: Rub off the bark with the back of a knife. Soak slices in water 2 hours to remove bitterness before cooking.

Growing Notes

Direct sow in spring or fall in a sunny location with deep, loose, fertile soil. Soak seeds 24 hours in warm water before sowing to improve germination. Cover very lightly — burdock needs light to germinate. Thin weak seedlings. Pinch off flowers as they appear to encourage root production. Mulch to suppress weeds.

Harvest: Roots ready when 12–16 inches long. Keep extra soil on harvested roots to prolong freshness. Young roots can be eaten raw.
