Just read your tips on oak leaf hydrangeas. I live in Zone 8-9. (North of Houston, TX) and my oak leaf absolutely loves my yard. It blooms in April-May and is tall, wide and beautiful. It sits facing north under partial shade of a pin oak tree. So it is possible to have a happy oak leaf south of zone 5.
