Bok Choy
Brassica rapa subsp. chinensis 'Pak Choi'
vegetableBok choy, or pak choi, is a non-heading Asian cabbage with crisp, succulent white stalks and tender deep-green leaves, prized for stir-fries, soups, and braises. A quick cool-season brassica, it matures in around 50 days, with baby heads ready even sooner, and it bolts under summer heat and long days.

🌱 Growing Guide
Direct sow or transplant in the cool weather of spring or fall, giving full sun to part shade, fertile soil, and even moisture, since drought or heat stress triggers premature bolting. Fall is the most reliable season; for spring crops, harvest young before summer heat arrives.

🌾 Harvest & storage
Cut the whole plant at the base once the stalks are crisp and full, or pick outer stalks as needed for a longer harvest. Baby heads are ready in about 30 days and resist bolting better than mature ones; bok choy tolerates a light frost.
🥗 Nutrition & benefits
Bok choy is low in calories and an especially good source of vitamins C and K, with about a third of the daily vitamin K in one cup, plus vitamin A as beta-carotene, folate, calcium, and potassium.
