Central Florida is not Tampa, etc.
The Tampa area is NOT central Florida. The continued assertion that it is part of central Florida is a major contributor to the failures of novices and the naive. The Tampa area is zone 10. Central Florida is zone 9. And northern Florida is zone 8.
Zone 10 limited plants will die in central Florida's zone 9 without protection.
As an example (the straw that broke this camel's post), the first touted "great landscape tree" in the thread linked below, Tabebuia, is listed by Floridata with a northern zone limit of 10 (9 with protection). Since it theoretically will survive in zone 9 with protection, this may NOT be the best example; however, it will do to make the point.
