Lee and Collier require natives from a list. You can use live oaks, laurel oaks Gumbo Limbo and Sabal Palms among others. The oaks seem to be the most popular since they pretty much grow wild and are not that expensive. I have several around my house that just came up. The problem most developers don't consider is they get real big (round) so that little shrub you put in the parking lot medians soon takes over the lot. In the community my wife manages they are takling them out. They need to succumb to a mystery disease first but a little "vitimin G" will do it.
