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's leaf is strap-shaped, with a waxy coating, and the leaves are alternately arranged on the stem; these fleshy blades are often bluish green in color. Most tulips produce only one flower per stem, but a few species bear multiple flowers on their scapes (e.g. Tulipa turkestanica).he tulip's large flowers usually bloom on scapes with leaves in a rosette at ground level and a single flowering stalk arising from amongst the leaves.Tulip stems have few leaves. Larger species tend to have multiple leaves. Plants typically have two to six leaves, some species up to 12.
