What is a "bulb"?
A bulb is a type of underground storage organ found in certain plants, typically consisting of a short stem surrounded by thick, fleshy leaves or scales. Bulbs serve as a food reserve for the plant and enable it to survive adverse conditions such as drought or cold weather. Examples of plants that grow from bulbs include onions, tulips, daffodils, and garlic. Bulbs are planted underground, where they remain dormant until favorable conditions trigger their growth, at which point they send up shoots to produce leaves, flowers, and eventually seeds. Bulbs are commonly used in landscaping and gardening to add color and beauty to outdoor spaces.
