I have a few Afican Tulip trees in my property in the Virgin Islands. The ones I have are over 60 ft. tall and the blooms are gorgeous.
They sit on an acre and not close to house. I don't like to have any trees, branches overhanging the roof.
Good luck with whatever you decide.

I planted crepe myrtle - comes in several colors

Thanks for the thoughts. I am going to hold off for now. "Invasive" does not sound like a term I want associated with decorative trees. I was not familiar with the tree but it came up on my computer and looked beautiful and great for shade. Alas.....
