Tulips are spring-blooming perennials that grow from bulbs. Depending on the species, tulip plants can be between 4 inches (10 cm) and 28 inches (71 cm) high. The tulip's flowers usually bloom on scapes with leaves in a rosette at ground level and a single flowering stalk arising from amongst the leaves.
They normally mean a declaration of love, not love itself, though. Red tulips mean love and fame. Multi-colored tulips are supposed to represent people with beautiful eyes, and therefore beautiful souls. (The eyes are the window to the soul.) yellow tulips symbolize happiness in one's life.
