it is salvia greggii ,,, an annual someplaces and a perrenial other places .
some of the other " annual " salvias reseed so easily they may as well be perrenials , you always have them
when I lived in CT , the datura was an annual , here in Florida they hang on for years and grow into small trees, and sprout all over the place .
Pepper plants last for years here ... only a few months in other places
pentas makes hedges and never dies
some plants are considered annuals here in Florida becaue they cannot make it thru a summer .
