Allamanda cathartica

Family: Apocynaceae

Common name: Golden trumpet

This plant is a vigorous, rambling woody climber that does not twine or have tendrils. The wavy-margined, obovate leaves are long and are arranged in whorls of 2 to 4 large, glossy, leathery leaves, creating a dramatic backdrop for the striking flowers. It typically blooms during the summer and fall. The large, trumpet-shaped flowers have five overlapping petals that flare widely, and they come in both single and double forms. The clusters of flowers appear at the tips of new shoots, with each cluster containing one to several flowers.

This plant is primarily used as a landscape ornamental due to its vibrant blooms. In traditional medicine, it is used to treat liver tumors, jaundice, and malaria. The leaves are used to treat coughs and headaches, while the latex has medicinal applications, such as treating colic and functioning as a purgative.
