Bulbs
A true bulb is a thickened, fleshy bud usually emitting roots from its underside. The stems, flowers and foliage will grow from the crown. Sometimes they may show a hint of surface mold on the exterior but this is usually not a problem as long as the bulb is still firm. The term bulb applies to a large class of flowering and ornamental bulbous-like plants in their dormant condition such as corms, tubers, rhizomes and pips.
Examples: Lilies, Tulips, Onion.
