It is a MANDAVILLA I don't know its Latin name I have one in the dining room/plant room I finally bought the 8 inch pot on sale at the end of season 2yrs ago it still set me back $20 I bring it in for winter and she's about 5 ft tall now the blooms are big and beautiful and a scent is from Heaven The first time I saw them was outside Atlanta,Georgia as a privacy fence I water it when the dirt is dry down to the depth of 2 inches our winters in ohio are to severe to leave it outside so I just change her into a bigger pot to prevent her getting pot bound
