Bok Choy/Shanghai Green seeds produce a compact, tender variety of bok choy prized for its smooth, jade-green spoon-shaped stalks and soft, mild leaves. Unlike the white-stemmed types, Shanghai Green's pale green stems blend seamlessly into its leaves, giving the whole plant a uniform, elegant appearance. The flavor is sweeter and more delicate than traditional bok choy, with a crisp, juicy bite that holds up beautifully in high-heat cooking without turning bitter.

Growing Guide

Shanghai Green bok choy reaches maturity in 45 to 50 days, making it one of the faster-maturing brassicas in the garden. It performs best as a cool-season crop, thriving in spring and fall when temperatures stay between 50°F and 70°F. Hot weather can cause bolting, so time your sowings accordingly — direct sow 4 to 6 weeks before your last frost date in spring, or 6 to 8 weeks before your first frost in fall.

Choose a location with full sun to partial shade (partial shade is welcome during warmer shoulder seasons). Direct sow seeds ¼ inch deep, then thin seedlings to 6 to 8 inches apart in rows spaced 12 inches apart. Shanghai Green adapts well to container growing, making it an excellent choice for patio gardens and raised beds. A loose, fertile, well-draining soil with consistent moisture and a pH between 6.0 and 7.0 produces the best results. Side-dress with compost midseason if growth slows. Difficulty level: beginner-friendly.

Harvest & Use

Harvest Shanghai Green when plants are 4 to 8 inches tall — younger plants are especially tender and sweet. Cut the entire head at the base, or harvest outer leaves individually to extend production from a single plant. Leaves begin to toughen and the plant may bolt if left too long in warm conditions, so harvest promptly once heads reach a good size.

In the kitchen, Shanghai Green is a workhorse. The stems stay crisp when stir-fried at high heat, while the leaves wilt down quickly into soups, noodle dishes, and braised preparations. It pairs naturally with garlic, ginger, sesame oil, and soy-based sauces. It can also be eaten raw in slaws or salads when harvested young. Store unwashed heads in a damp paper towel inside a sealed bag in the refrigerator for up to one week.

A fast-growing, reliable brassica with genuine culinary versatility, Shanghai Green bok choy rewards both first-time gardeners and experienced growers with consistent harvests across multiple seasons.
