Traditional Korean radish with exceptional flavor.
Alpine, with its 5–8" x 2–2 1/2" roots, is the most common type grown for kimchi in Korea. The smooth, attractive roots are white with green shoulders, and are sweeter than the long, white, Japanese types. A better choice than the long types for rocky soils and better flavor, especially in warm weather. Bolt tolerance makes it suitable for spring and summer sowings. For fresh use, pickling/fermenting, and storage. Avg. 40,200 seeds/lb. Packet: 100 seeds.
SCIENTIFIC NAME: Raphanus sativus var. longipinnatus CULTURE: Daikon and Korean radishes require friable, well-drained soils with a pH range of 5.8–6.8. Work soil deeply, in raised beds if possible, for straight roots and ease of harvest. Sow 10 seeds/ft., thinning to 4–6" apart, rows 18" apart. Note planting seasons in variety descriptions to reduce bolting. HARVEST AND STORAGE: Daikon and Korean radishes are brittle; use gardening forks or undermine and lift roots carefully. Cut tops 2" above crowns, wash, and refrigerate. Can be stored at 32°F (0°C) and 95% relative humidity for 6–10 weeks. AVG. DIRECT SEEDING RATES: 1 oz./260', 3.9 oz./1,000', 5 1/4 lb./acre at 6 seeds/ft. in rows 24" apart, or 7 lb./acre in rows 18" apart. SIZED SEEDS: All seeds are unsized. SEED SPECS: SEEDS/LB.: 23,400–51,500 (avg. 38,600). PACKET: 100 seeds, sows 16–17'.

Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
