Beans are a legume, which is the fruit or pod of the botanical family Leguminosae. The potato tuber (Solanaceae family) is actually the greatly enlarged tip of the underground stem of the potato. Cucumbers are members of the Cucurbitaceae family, which includes most melons and gourds. Lettuce (Asteraceae family) is a salad vegetable normally grown for its leaves. Cabbage, broccoli, and cauliflower are all members of the Cruciferae family, also known as cole crops. Cabbage is grown for its leaves and broccoli and cauliflower are grown for their flower heads, which we eat before the flower buds bloom. Celery is in the Umbelliferae family, and the one you are familiar with is an herb grown for its edible leaf stalks.
