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.

Tulip Poplar-Liriodendron tulipiferaMagnolia Family (Magnoliaceae). The tulip poplar (also called tulip tree) is actually more closely related to magnolia than either a tulip or a poplar.The reference to tulips comes from the shape of the greenish yellow and orange flowers.lthough the common name suggests it, tulip poplar is not a poplar but in the genus Liriodendron. Leirion is Greek for a lily and dendron is a tree. The specific epithet, tulipifera, refers to the shape of the flowers. Tulip poplar has also been called canoe tree because Native Americans used it to make dugouts.
