Sometimes called cathedral bell, this vigorous and irrepressible vine is a native of tropical America, where it grows as a strong woody perennial. It may be grown in large pots for standing outdoors in summer, and will behave as a perennial if kept indoors in winter at about 7C (45F). In a very mild winter plants may survive and remain virtually evergreen, but they're usually grown as annuals on a wall, fence or pergola. Plants have a tropical appearance, with lush foliage and 8cm (3in) flowers with prominent stamens. Once fully open, they're sweetly fragrant. The Royal Horticultural Society has given it its Award of Garden Merit (AGM).
