The Nature of Underground Bulbs:
Underground bulbs are specialized storage organs found in a variety of plants. They have a distinctive structure that sets them apart from other plant parts. The bulb is composed of modified leaves that tightly encase a miniature plant, complete with embryonic leaves, stems, and flower buds. These remarkable structures have evolved as a survival strategy, allowing plants to endure harsh conditions and grow anew when the time is right.
Types of Underground Bulbs:
There are several types of underground bulbs, each with its own peculiarities. The most common ones include:
True Bulbs: These bulbs consist of layers of fleshy scales that surround the central shoot, like the familiar tulips and daffodils.
Corms: Corms are solid, swollen underground stems that are covered with a thin, papery tunic, as seen in crocuses and gladiolus. Rhizomes: Although not true bulbs, rhizomes are horizontal, underground stems that produce roots and shoots along their length. Irises and lilies are examples of plants with rhizomes. Tubers: Potatoes are a well-known example of tubers, which are thickened, fleshy underground stems that store nutrients. Tuberous Roots: These roots, found in plants such as dahlias and sweet potatoes, are swollen and store nutrients like tubers. The Life Cycle of Underground Bulbs:
Underground bulbs follow a remarkable life cycle. During the growing season, the plant utilizes the stored nutrients within the bulb to produce leaves, stems, and flowers. Once the growing season ends, the aerial parts of the plant wither away, and the bulb enters a period of dormancy. During this resting phase, the bulb conserves energy and prepares for the next growing season. As conditions become favorable, the bulb initiates growth again, sending forth new shoots to renew the cycle.
Cultivating Bulbs for Ornamental Beauty:

From the cheerful tulip fields of the Netherlands to the delicate bluebells carpeting woodlands, the beauty of these underground gems enchants and inspires.
