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.
The tulip tree is one of the largest of the native trees of the eastern United States, known to reach the height of 60 m (190 ft), with a trunk 3 m (10 ft) in diameter; its ordinary height is 20 to 30 m (70 to 100 ft). It prefers deep, rich, and rather moist soil; it is common, though not abundant, nor is it solitary.
