• Article number: ALLACA01

Allamanda cathartica is an evergreen tropical climbing plant belonging to the dogbane family (Apocynaceae). Native to northern South America, particularly Brazil, it is widely admired for its large golden-yellow trumpet-shaped flowers and long-lasting display of blooms. In tropical and subtropical climates it grows as a vigorous climber, while in cooler regions it is commonly cultivated as a container or conservatory plant.

The plant produces long, flexible stems that readily climb over trellises, pergolas, or other supports. Its glossy dark green leaves are usually arranged in whorls or opposite pairs, creating an attractive contrast with the bright flowers. The large trumpet-shaped blooms are vivid golden yellow and typically measure between 8 and 12 centimetres across.

Allamanda cathartica thrives in a warm, sunny location with fertile, well-drained soil. Regular watering during the growing season encourages vigorous growth and abundant flowering, while waterlogged conditions should be avoided. A sheltered position protected from strong winds helps maintain healthy foliage and long-lasting blooms.

Under favourable conditions, the plant flowers continuously throughout the warmer months. In its native habitat, the flowers attract a variety of pollinators, including bees and butterflies. Its lush growth and spectacular floral display make it an outstanding feature for conservatories, patios, tropical gardens, and other warm outdoor settings.

Golden Trumpet is not frost hardy and cannot tolerate freezing temperatures. In temperate climates, it should be overwintered in a frost-free environment. Like many members of the Apocynaceae family, the plant contains a milky sap that may cause skin irritation and is toxic if ingested.

With its abundant flowering, glossy foliage, and unmistakable tropical character, Allamanda cathartica is an excellent choice for anyone seeking a colourful and exotic ornamental plant.
