Chinese cabbage with small edible flowers
Choy sum is similar in appearance to other Chinese greens, but distinguished by its thin stems and small, yellow flowers. Choy sum is a smaller, delicate version of bok choy (see "bok choy"). It is often served boiled and covered with oyster sauce or used in stir fries and soups. Choy sum is one of the more popular leaf vegetables in Hong Kong.
