Water Bamboo

Water bamboo is a crisp, low-calorie aquatic vegetable commonly used in Asian cooking.

Water bamboo, also known as Zizania latifolia or Coba, is an aquatic vegetable popular in East Asian cuisine, prized for its crisp texture and mild, sweet flavor. It is the swollen stem of the grass infected by a specific fungus that prevents the plant from flowering and causes the stem to enlarge.
