Bulbs are underground storage organs of plants that help them survive through tough conditions. They are made up of layers of fleshy scales, which store nutrients and energy. Common examples of bulbs include tulips, daffodils, and onions. When the right conditions arise, such as warmth and moisture, bulbs can sprout and grow into beautiful flowers or delicious vegetables. Planting bulbs is a simple and rewarding gardening activity. They can be placed in the ground during the fall or spring, depending on the type. With proper care, bulbs will bloom year after year, adding color and life to gardens and landscapes.
