I have tried to grow Giant Granadilla here but it is very sensitive to cold and I lost it one frosty night. I have tried the Florida native Passaflora incarnata (maypop) but spent most of the time trying to kill it as it is very invasive. Most folks use it as a butterfly plant. I now grow Passaflora edulis. It produces good fruit and is not invasive. There are two types; one produces purple fruit and the other yellow fruit.
