A bulb is a tuberous food storage organ and a central part of reproduction for a specific class of plants.
MaximumYield explains Bulb
Bulbs go through two stages of growth and development, the vegetative and the reproductive. During the vegetative state a bulb begins the growth cycle and the plant develops leaves and reaches the blooming stage. The reproductive stage begins when the plant blooms.
Following the blooming stage, a plant enters into a growth stage where the plant gathers and the bulb stores nutrients for the following year. This phase of development lasts about six weeks.
After the plant completes its life cycle the bulb will go through a period of dormancy and will require certain environmental conditions before it will sprout and grow again. This includes a transition period between cold and warm weather along with a certain soil temperature and length of available day light.
Lilies, tulips, and daffodils are notable spring bloomers that develop from bulbs.
