In Indonesia, this flower is called the "Golden Trumpet Flower". But scientifically, this flower is called Allamanda cathartica.
This flower is a type of ornamental flower that can beautify your home page. Allamanda cathartica is found in Central and South America. But in Asia, this flower can also grow well.
Here are some photos of Allamanda Cathartica that I took. I reduced the photos from their original size.
