Shallot bulbs Hippeastrum (amaryllis) bulb. In botany, a bulb is a short underground stem with fleshy leaves or leaf bases [1] that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just bulbs.
Bulb: A short vertical underground stem with fleshy storage leaves attached, e.g. onion, daffodil, and tulip. Bulbs often function in reproduction by splitting to form new bulbs or producing small new bulbs termed bulblets. Bulbs are a combination of stem and leaves so may better be considered as leaves because the leaves make up the greater part.
As a result, a corm cut in half appears solid inside, but a true bulb cut in half reveals that it is made up of layers. [3] Corms are structurally plant stems, with nodes and internodes with buds and produce adventitious roots. On the top of the corm, one or a few buds grow into shoots that produce normal leaves and flowers.
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
The bulbous buttercup gets its name from its distinctive perennating organ, a bulb-like swollen underground stem or corm, which is situated just below the soil surface. After the plant dies in heat of summer, the corm survives underground through the winter.
The plants form attractive clumps of ivy, lance, or heart-shaped foliage. There are currently more than 20 species of cyclamen, but hardy cyclamen typically is considered the easiest to grow.
In stem tubers the order is reversed, with the distal end producing stems. Tuberous roots are biennial in duration: the plant produces tubers the first year, and at the end of the growing season, the shoots often die, leaving the newly generated tubers; the next growing season, the tubers produce new shoots.
