Vigna unguiculata, also called the Yard-long Bean, the Snake Bean, the Asparagus Bean and various other weird names, is an Asian green bean that grows very well in Florida.
The vines grow really long with little or no care. Make sure you have plenty of climbing room for them.
Snake beans take a little while to get started. For a few weeks, they are just little bean plants. And then they jump start their growth.
Bugs leave them alone for the most part and the vines are good at climbing on whatever is handy.
