原生地・分布（英語）:

説明（英語）: Genus of 30 species of deciduous or semi-evergreen climbers, shrubs, and small trees found in woodland from Mexico to tropical South America. They are grown for their salverform flowers, each with 5 petal lobes, produced in terminal racemes or from the uppermost leaf axils, sometimes forming panicles. Simple, elliptic leaves, with prominent veins, are borne in whorls or opposite pairs. Where temperatures fall below 10-13°C (50-55°F), grow in a warm or temperate greenhouse. In warmer areas, grow in open beds, in borders, or as specimen plants; climbing species look spectacular cascading from a tree.

耐寒性（英語）: Frost tender.
