Flower

The flowers of a tulip tree (like the common name suggests) resemble a tulip.  They are perfect, showy, Monoecious, but high in the tree. They are usually about 2.5 inches long, and have yellow green petals and an orange corolla. 

The tulip tree blooms in late spring or early summer, and it has a very pleasant fragrance.  The trees usually will not bloom until they are 15-20 years old.

Bark

The bark is usually a light gray and green color.  It is smooth on young trees but starts to develop flat topped ridges and white colored ridges as it matures. Sapsucker holes are common on old trees.

Fruit

The fruit of a tulip tree or yellow poplar is elongated, 1-3 inches long, and brown with a dry and hard covering.  The fruit is not showy, but it attracts birds and may cause significant litter.

Other

Tulip trees are VERY large in size; large trees of 150 feet or more are very common, and they are known as one of the tallest of all broadleaf trees in the eastern United States.  They have very massive trunks and are ovate or pyramidal when young. However, older trees are more irregular and are branchless until 'quite some distance up.'

The word "Liriodendron" comes from the Greek word meaning "lily tree."   "tulipifera"  Comes from the word meaning "tulip bearing."

Pests and diseases

Aphids can cause cosmetic problems; their honeydew secretion can build on the tree and other nearby structures and, although the mess will not harm the tulip tree, it is an annoyance.

Tulip Tree scales are brown and oval shaped. They also secrete a honeydew which may cause a sooty mold to build. 

The Tulip Tree is attacked by many different forms of the Canker Disease.  By pruning out infected branches and keeping the tree well maintained you can prevent cankers.
