Allamanda cathartica, commonly called golden trumpet, common trumpetvine, and yellow allamanda, 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.
It is cultivated as an ornamental plant for its large, fragrant flowers. It is a vine that requires a trellis or a fence for support. It does not twine, nor does it have tendrils or aerial roots. It can be pruned into a shrub form. If not pruned it can sprawl to a height of 20 feet.
