Corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat (perennation).
Such tubers tend to form at the sides of the parent plant and are most often located near the soil surface. A below ground stem tuber is normally a short-lived storage and regenerative organ developing from a shoot that branches off a mature plant. The new tubers are attached to a parent tuber or form at the end of an underground rhizome.
Plants that form underground storage organs, including bulbs as well as tubers and corms, are called geophytes. Some epiphytic orchids (family Orchidaceae) form above-ground storage organs called pseudobulbs, that superficially resemble bulbs. [citation needed] Nearly all plants that form true bulbs are monocotyledons, and include: [4]
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 offspring or new tubers are attached to a parent tuber or form at the end of a hypogeogenous (initiated below ground) rhizome. In the autumn the plant dies, except for the new offspring tubers, which have one dominant bud that in spring regrows a new shoot producing stems and leaves; in summer the tubers decay and new tubers begin to grow.
Some flower bulbs do well in hot climates: Lilies, Caladiums, Dahlias, Gladiolus, Narcissus (plant) and daffodils.To grow cold weather flower bulbs like Tulips and crocus in hot climates, gardeners must dig up the bulbs and store them in the cold for 3-4 months before replanting.
This is particularly common in species that develop underground storage organs, such as bulbs, corms and tubers. Tulips and lilies are examples of plants that display offset characteristics by forming cormlets around the original mother corm. In the UK, the term 'bulbils' is used for lilies.
Bulbine bulbosa is a perennial herb that grows in tufts 27–75 cm (11–30 in) high with thick, fleshy roots and usually a bulb-like tuber.There are between three and seven leaves, channelled to more or less cylindrical, tapering and hollow, up to 30 cm (12 in) long and 1–5 mm (0.039–0.197 in) wide.
