Make Like A Tree and Get Out of Here

Q: Name a tree. In the very middle of the word insert a homophone of another tree. The result will be a new word describing what everyone wants to be. What is it?

What everyone wants to be? Not me.

Edit: “Not me” would be “you” which is also a homophone for the letter U.

A: POPLAR + YEW(U) –> POPULAR
