Liriodendron tulipifera - Tulip Tree

The tulip tree is a large, fast growing deciduous tree to 70' x 30'. Pyramidal in youth, oval with age. Very popular native from the east coast. Not sure if its the flowers or the leaves.... but are pretty interesting. Grows a very tall and straight trunk. Fall color is pretty good but not always.





Leaves are alternate, simple, 3-8", lobed with a flat tip (truncated). Very easy to identify this tree from the leaf, nothing else like it.



Stems are stout, greenish-brown. They have very distinct buds, stipules (see below) and stipular scars. The buds are large, valvate, looking like a duck bill. The stipules are leaf like growths that emerge at the base of the leaves and soon fall off leaving a scar on the stem.



Flowers are quite pretty but not always easy to see. They are about 2-3" tall and 2" wide with 6 more or less greenish yellow petals. The inside of the petals is a large orange spot. They resemble tulips hence the common name.




Fruit is a collection of  achenes looking somewhat like a cone. This tree is from a very primitive group of angiosperms related to magnolias. 





Trunks are very straight and tall. Thin ridges, grayish colored. 





Misidentification:
look for the truncated leaves.
