Exotic passion flowers look as though they would be tropical plants, but they can actually be grown almost anywhere, including much milder areas. You may even find these delicate vines growing along the side of the road. In fact, some passion flowers species are becoming invasive in warmer climates.
The genus Passiflora contains over 400 species, so the common name Passion Flower can be a bit confusing.
To muddle matters further, most are vines, but some are shrubs, annuals, perennials and even trees and some also produce edible fruits. What they all share are exotic flowers that only remain open for about one day.
