Allamanda cathartica, commonly known as golden trumpet, is a tropical flowering plant native to Central and South America. It belongs to the Apocynaceae family and is recognized for its vibrant yellow, funnel-shaped flowers that bloom throughout the year in suitable climates. The plant can grow as a shrub or vine, reaching heights of up to 3 meters (10 feet). This species thrives in well-drained soil and prefers full sun to partial shade. While it is often used in gardens and landscapes for ornamental purposes, Allamanda cathartica is also known for its potential medicinal properties, although caution is advised as some parts of the plant can be toxic if ingested.
