Allamanda cathartica, commonly called golden trumpet,^[2] common trumpetvine,^[2] and yellow allamanda,^[2] is a species of flowering plant of the genus Allamanda in the family Apocynaceae. It is native to Brazil. This plant is cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius.

The species is cultivated as a house plant. It requires a soil rich in organic matter, temperatures of not less than 18 °C (64 °F) during the growing season, plenty of moisture, and bright light but not direct sunlight. During the rest season from October to March, the plant should be watered more sparingly and can endure temperatures down to 13 °C (55 °F). It should be repotted every year until it is in a container of 40 to 50 centimeters (16 to 20 in). Propagation is by cuttings taken from April to May.^[5]
