Tulips bloom to spread and receive pollen, like other flowers. They receive and spread pollen at the same time because like many other plants, tulips are hermaphrodites.
Tulips spread by bulbs, rather than by seed.
Sometimes chipmunks (and squirrels) will dig up bulbs that are close to the surface, and then store them underground in a different location. If a chipmunk is scared off before it can store the bulbs, the bulbs are abandoned in random spots and take root. Tulips do not spread on their own, except in the sense that they form new bulbs each year (much like a garlic clove turns into a head of garlic).
