I am not familiar with these trees, so looked it up. Based on what I read, prior to planting, you may want to check with the Dept. of Agriculture or a Master Gardener:

We now know that African tulip trees are invasive and damaging to ecosystems. They grow extremely fast; in Puerto Rico they can increase 2” in diameter per year, shooting up from the forest floor and outcompeting other plants for sunlight. They can be a notorious pasture pest, springing up when land is cleared and creating a field of tulip trees with little else. Prolific seeders, their papery oatmeal-like seeds blow in the wind for miles. But perhaps what makes these trees most invasive is their shade-tolerant seedlings.

Shade tolerance means a seedling can sprout in an intact, shaded forest, then invade and dominate the landscape. This contrasts with many other invasive species that depend on disturbances and light gaps to gain a foothold. African tulip invades either way.
