Since they were first described in Europe in the 16th century, passionflowers have held a special fascination among plant collectors for their bold, beautiful, complicated blossoms and delectable passionfruits. Most are perennial climbers, but some are trees, shrubs, herbaceous plants, or even annuals, and all lend a dramatic, tropical flavor to any situation. Since they have such a broad range of cultivation requirements, passionflowers can be grown by just about anyone, and cold-hardy species can be grown outdoors year-round. This authoritative, comprehensive volume describes 207 Passiflora species and 31 hybrids. A chapter is devoted to the remarkable coevolution of passionflowers with Heliconius butterflies, which many passionflower enthusiasts now raise alongside flowering vines in the greenhouse. As lushly illustrated as it is informative, Passiflora: Passionflowers of the World reveals the immense variation found among members of this extraordinary genus.
