Bulbs, rhizomes and tubers

Although the term “bulbs” is used for many plants found in this form on the market, not all of them are bulbs. In reality, they are sometimes corms, rhizomes or tubers. We use the term bulb because, in the garden, the way they are cultivated is similar.

A bulb is a plant in its embryonic state with a stem surrounded by fleshy leaves.

Corms, also called Cormus, are reserve organs very close to the bulbs. However, they are more flattened. They consist of a swollen stem, where nutrient reserves are stored.

The tuber is a piece of root or stem that has swollen to serve as a reserve organ.
