Blue Passion Vine is an exotic-looking twining vine famous for its intricate, star-shaped flowers. It's a member of the passionflower family and a popular ornamental climber. It produces striking 3–4 inch blooms with white or pale pink outer petals and a dramatic central crown of blue, purple, and white filaments. They are lightly fragrant and bloom from early summer through fall, often in flushes. Glossy, dark green, palmately lobed leaves provide a lush backdrop.
