Bok choy, pak choi or pok choi is a type of Chinese cabbage. Chinensis varieties do not form heads and have green leaf blades with lighter bulbous bottoms instead, forming a cluster reminiscent of mustard greens. It has a flavor between spinach and water chestnuts but slightly sweeter with a mildly peppery undertone.

Sow bok choy in spring and again in late summer for harvest in fall. Sow in double rows, with rows spaced 10 inches (25 cm) apart. Plant seeds 2 inches (5 cm) apart and barely cover them with soil. Gradually thin to 8 inches (20 cm) apart.

Chinese cabbage is a cool-weather plant that will bolt and go to seed quickly in warm weather and long days; grow Chinese cabbage in spring or autumn in temperatures ranging from 45° to 75°F (7-24°C). Sow seed 4 to 6 weeks before the average date of the last frost in spring.
