If a single plant of similar stature and flowers is desired, consider flatwoods plum, Prunus umbellatus. Based on BONAP and ISB maps, the range of this species covers much of the southern and south central US with some outliers to the north and west. In Florida, it has been documented in many counties in the northern half of the state, and this author is aware of it being in others.  It appears to be appropriate to consider this species native throughout this part of the state. Plant as a screen where its suckers are welcome (woodland edges, casual but large garden settings)
