Rare and hard-to-find, Australian Two-Tone Passion Flower has amazing flowers that last for three days with the color changing from white to brilliant orange as the flowers age. Its a vigorous climbing plant with small leaves that measure about an inch across. Here in New England, its a three-season bloomer with spectacular flowers from spring to fall. It prefers drier soil so allow the surface of the soil to dry out between waterings to keep the plant roots healthy.
