Stem vegetables are a type of vegetable where the edible portion of the plant is the stem or stalk. These vegetables are characterized by their long, slender shape and fibrous texture. Some examples of stem vegetables include asparagus, celery, rhubarb, and bamboo shoots.

Stem vegetables are often low in calories and high in fiber, making them a nutritious addition to a balanced diet. They can be eaten raw or cooked and are often used in a variety of dishes, such as salads, soups, stir-fries, and stews.

It is important to note that not all vegetables with stems are stem vegetables. Some vegetables, such as broccoli and cauliflower, have edible stems but are classified as cruciferous vegetables because they are members of the Brassicaceae family.
