Alpine
(F1) Radish Seed
Product ID: 2473
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.
