Passiflora (Passion Flower)
Exotic passion flowers look as though they are tropical plants, but they can be grown almost anywhere, including much milder areas. You may even find these seemingly delicate vines growing along the side of the road. Some passion flower species are becoming invasive in warmer climates.
The flowers are extremely attractive to butterflies and other pollinators. In regions where they are not hardy, passion flower plants are often grown in pots and moved indoors to overwinter.
