description_en: Genus of more than 400 species of mostly evergreen tendril climbers, and a few annuals, perennials, shrubs, and trees. They occur usually in tropical woodland, on rocks, and in grassland, mainly in tropical North, Central, and South America, and also in tropical Asia, Australia, New Zealand, and the Pacific islands. The leaves are usually alternate, simple or 2- to 9-lobed (mainly 3- or 5-lobed), elliptic to rounded or broadly ovate, and often with prominent nectar glands on the margins or stalks. The exotic flowers are mostly produced singly, sometimes in racemes, from the upper leaf axils. Each has a wide, tubular base and 10, sometimes 5 tepals, that spread out flat, reflex, or form a saucer or bowl shape. A stalk in the centre of each flower bears the ovary and stamens, and is surrounded by one or several rings of fleshy filaments (the corona). The ovoid to spherical, edible, usually yellow fruits are very variable in size. Hardy species are ideal for clothing a wall or trellis. In frost-prone areas, grow tender species in a cool to warm greenhouse. In warmer climates, train over a pergola or arch, or through a tree.

hardiness_en: Fully hardy to frost tender. P. ‘Amethyst’, P. manicata, and P. ‘Star of Bristol’ may survive temperatures down to 0°C (32°F) if the wood has been well-ripened in summer.
