Golden Trumpet Overview

Originating in the jungles of Brazil, Allamanda, widely known as Golden Trumpet is propagated from stem cuttings. As a vine and a shrub, it flourishes in warm and moist climates. Growing thickly, it gets covered in yellow bell-shaped flowers, making it a lovely option for a hedge screen​. Be cautious when growing or handling Allamanda, as they secrete a white sap when damaged, which can be harmful. This vigorous tropical vine is a popular conservatory plant, producing clusters of striking yellow flowers contrasting with shiny dark green leaves.
