Estimated Native Range
Summary
Allamanda cathartica, commonly known as Golden Trumpet, is a perennial climbing plant native to the tropical forests of central and eastern South America. It is often cultivated in subtropical and tropical regions around the world. This species typically sprawls to a height of 20 feet if not pruned, and can be trained into a shrub form. It is characterized by its large, trumpet-shaped, bright yellow flowers that bloom throughout the year in its native habitat, with peak flowering in the summer. The showy flowers and its ability to be shaped make it a popular ornamental plant.
Golden Trumpet is valued for its vibrant flowers and versatility as either a climbing vine or a pruned shrub. It is often used in trellises, fences, and as a houseplant in cooler climates. In cultivation, it requires a soil rich in organic matter, consistent warmth with temperatures not dropping below 18 °C (64 °F) during the growing season, and high humidity. It thrives in bright, indirect light and needs plenty of moisture, with reduced watering from October to March. It should be repotted annually until it reaches a substantial size. While it prefers full sun, it can tolerate partial shade. Propagation is typically done through cuttings in the spring. Gardeners should be cautious as Allamanda cathartica can become invasive outside its native range, particularly in warm climates such as Florida in the United States.CC BY-SA 4.0
