It is a Bougainvillea. The bougainvillea is a thorny vine or bush with colorful modified leaves around the flower. Native to South America, it is also known as Buganvilla (Spain), Bugambilia (Mexico, Guatemala, Philippines, Cuba) or Pokok Bunga Kertas (Indonesia), Napoleon (Honduras), Trinitaria (Colombia, Panama, Venezuela, Puerto Rico and Dominican Republic), Papelillo (northern Peru), Veraner (Colombia, Panama, Nicaragua, El Salvador and Costa Rica) or Santa Rita (Paraguay, Uruguay, Bolivia, Brazil and Argentina).

The actual flower of the plant is the small and white bloom at the center, surrounded by colorful bracts. Bracts are modified leaves associated with a reproductive structure, such as an inflorescence axis, flower or cone scale.

The Bougainvillea is a sun-loving, proliferous and hardy plant. It is not a fragrant flower, but it does not require much care and the colors are vivid and there are several colors to choose from.
