Cool season annual. 45 days. This loose-leaf Chinese cabbage variety has medium green, glossy leaves and pale green midribs. In frost-free areas, it can be sown all year long but avoid planting in the middle of a hot summer. For larger heads, harvest in 60-70 days. Stir-fry or steam. Chinese and Japanese cooks often use loose-headed cabbages for pickling. Chinese cabbage prefers cool temperatures for its main growing season. Prepare fertile, well-drained soil. In temperate areas sow seeds in spring/summer after last frost or late summer/early fall. Plant year round in tropical areas. Keep soil moist. Fertilize as needed. Exposure to frost or prolonged temperatures below 50°F may result in bolting. Harvest at any stage. Note: Chinese Cabbage requires vernalization. Bud differentiation and bolting results from low temperatures of 41°F for a week or 50°F for two weeks. For spring harvest, transplant seedlings with 5-7 true leaves raised at 73-75°F during the day and over 53°F at night. Providing plants with adequate water and fertilizer after transplanting will promote faster growth. Use in salad, sukiyaki, ohitashi, yosenabe, stir-fry, soup and pickling. Approximately 4480 seeds per ounce.
