Allamanda cathartica, commonly known as the “golden trumpet” or “yellow allamanda.” It is a tropical vine or shrub native to South America that is often cultivated for its showy, trumpet-shaped, golden-yellow flowers.

The plant can grow up to 6 meters (20 feet) tall and has large, glossy, green leaves. Its flowers are around 10 cm (4 inches) in diameter and are produced in abundance in the summer and fall. The flowers have a pleasant fragrance and are popular with butterflies and other pollinators.

Allamanda cathartica is commonly grown as an ornamental plant in gardens and landscapes in tropical and subtropical regions around the world. It prefers full sun and well-drained soil and can be propagated from seeds or cuttings. The plant contains toxic compounds, including cardiac glycosides, so care should be taken when handling it.
