Bok choy, is classified as a cabbage. Nonetheless, bok choy bears little resemblance to the round European cabbages found in western markets, or to Napa Cabbage for that matter.
Green cabbage has tightly wrapped pale green, thick and pliable leaves. Round, solid and almost white in the center, this vegetable is heavy for its size.
Kale is a member of the cabbage family, cousin to broccoli, collards and Brussels sprouts. Mature Kale is bold and peppery with a chewy texture, so it's rarely served raw.
Producing white leaves at the bottom and pale green leaves at the top, Napa cabbage leaves are somewhat crinkly. Superior in flavor compared to the common cabbage, Napa cabbage is milder.
Round, compact and heavy for its size, red cabbage boasts dark-red thick and pliable shiny leaves. The color of this cabbage has an affect on its slightly peppery flavor.
