Answer: I found the photo and the flower is called Passion Flower (Passiflora incarnata), sometimes called Maypop. It is a tender perennial vine (grows in zones 6-9) and typically grows about 15' per year. It prefers full sunshine and moist soil. You're in zone 6 so it should grow well for you as long as you provide winter protection. The top of the plant will die down with your first frost but if you mulch over the top of the soil after cutting back the dead vine, the roots should survive and send out new growth the following spring.
