Shallot bulbs
A bulb is an underground vertical shoot that has modified leaves (or thickened leaf bases) that are used as food storage organs by a dormant plant.
A bulb's leaf bases generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. The leaf bases may overlap and surround the center of the bulb as with lilies, or may completely surround the inner regions of the bulb, as with the onion. A modified stem forms the base of the bulb, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side.
Other types of storage organs (such as corms, rhizomes, and tubers) are sometimes erroneously referred to as bulbs. The correct term for plants that form underground storage organs, including bulbs as well as tubers and corms, is geophyte. Some epiphytic orchids (family Orchidaceae) form above-ground storage organs called pseudobulbs, that superficially resemble bulbs.
Plants that form true bulbs are all monocotyledons, and include:
- Onion, garlic, and other alliums, family Alliaceae.
- Lily, tulip, and many other members of the lily family Liliaceae.
- Amaryllis, Hippeastrum, Narcissus, and several other members of the amaryllis family Amaryllidaceae.
- Two groups of Iris species, family Iridaceae: subgenus Xiphium (the "Dutch" irises) and subgenus Hermodactyloides (the miniature "rock garden" irises).
Bulbil
Some lilies form small bulb-like fruits called bulbils in their leaf axils. Several members of the onion family, Alliaceae, including Allium sativum (garlic), form bulbils in their flower heads, sometimes as the flowers fade, or even instead of the flowers. The so-called Tree onion (Allium cepa var. proliferum) forms small onions which are large enough for pickling.)

Tree onions form clusters of small bulbs instead of flowers

Dormancy is a period in an organism's life cycle when development is temporarily suspended. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions.

Tubers are different types of modified plant structures that are enlarged to store nutrients. They are used by plants to overwinter and regrow the next year and to reproduce. Three different groups of tubers are: potato tubers, stem tubers, and root tubers.
