I've been looking through my Florida plant book and googling for Oaks that grow in this zone. It looks a lot like Quercus phellos (Willow Oak) which is native from New York to North Central Florida and west to Texas. My book says it has a fibrous root system making it easier to transplant than many other oaks so I might try moving it. Currently it's growing right up under a Magnolia tree and if it's an oak that's going to get to 50' I'd prefer it farther out in the yard.
