Allamanda cathartica, native to Brazil, is a tropical twining vine that can also be pruned to shrub form. It has leathery bright green leaves and trumpet/funnel shaped bright yellow flowers. The blooms are followed by prickly seed pods with winged seeds. This plant prefers bright sun to dappled shade and regular watering during the warm months. During the winter rest period it should be kept on the dry side.
