They create themselves. When you dig the bulbs in the Fall (if in cold area), you will see new bulbs. Some are very tiny but usually there is at least one that has some size to it. These are planted when you plant in Spring. If you are in a warmer area, they can just be left in the ground without digging. They can be divided in the Spring and planted where you want the new bulbs. Tiny ones should be planted pretty shallow. Please supply your location or planting zone when asking future questions since answer are different depending on that information.
