The word 'vegetable' has no precise botanical meaning in reference to food plants, and we find that almost all parts of plants have been employed as vegetables - roots (carrot and beet), stems (Irish potato and asparagus), leaves (spinach and lettuce), leaf stalk (celery and Swiss chard), bracts (globe artichoke), flower stalks and buds (broccoli and cauliflower), fruits (tomato and squash), seeds (beans), and even the petals (Yucca and pumpkin).
