All bulbous plants are perennial in their growth habit and have their food stored in their modified underground stems called bulbs. In other words, a bulb is a sharp-pointed, short, modified underground stem which are covered by fleshy succulent leaves, either in continuous or in loose arrangement. Some of the major bulbs used as vegetables are onions, leeks, and garlic.
