Perennial. This popular Chinese specialty herb is a vigorous perennial. It is grown for its young flower buds, long stems and slender flat deep-green blades that grow up to 14". All of these parts are edible including mature flowers and have a delicate garlic onion flavor. This variety is suitable for harvest from mid spring to early fall when grown in a greenhouse, and from late spring to late fall when grown in the field. Sufficient vegetative growth (1-2 years) plus low temperatures in winter and long summer days are needed for flowering. Generally, Chinese leek will not flower in the first growing season. Prepare fertile, well-drained soil. Direct sow seeds in late spring/ early summer after last frost in sun or partial shade. Keep soil moist. Fertilize as needed. If transplanting, do so when 5-6 leaves appear. Fully mature plants can grow 14-16" tall. Harvest by cutting just above ground level. For growing blanched leeks, only strong plants should be grown in this manner. Cover with a tunnel and exclude all light while continuing to provide all of the plant's other needs. Harvest as usual. Used in soups, stir-fries, tempura, dumplings, and salads. Excellent in egg dishes. Flowers are used as an edible garnish with dishes like sashimi. ~10250 seeds / oz.
