Tulip Tree

I've called a Japanese Magnolia a tulip tree for a really long time.  Eventually I figured out that what I was calling a tulip tree was actually a Japanese Magnolia.
But we moved to Tennessee and I found there actually is a tulip tree.  It is a tulip poplar and is the state tree of Tennessee.  The flowers are way up high on the tree and not very flashy.

The tulips that show up the best in this picture are to the left of the trunk.
