I'll have to get you in touch with My friends Mike's Parents. they practicly live in a forest up IN NE OK. Plenty of Moon Flowers, and a Cherry tree that Grows and looks like a Weeping willow.
The moon flowers are pretty Cool, white blossoms, that open as It get's dark. It also seems to be able to grow in just about any Oklahoma Soil.
If I may suggest, Make sure you get a soil sample test from Various locations around your property, as this might help you to decide what trees/plants to put where.
