Wombok (also called Chinese cabbage, napa cabbage, or wong bok) forms tall, barrel-shaped heads of crinkled, pale green leaves. It is faster to mature than European cabbage (8-10 weeks), milder in flavour, and excellent for kimchi, stir-fries, and salads. A cool-season crop that bolts rapidly in warm or long-day conditions.
