Begonia pavonina

Begonia pavonina, belonging to the family Begoniaceae and commonly known as the peacock begonia, is a captivating plant native to the montane forests of Peninsular Malaysia. This unique species thrives in the moist, shaded, cool understorey of its tropical habitat, where it has adapted to low-light conditions. The peacock begonia is renowned for its strikingly beautiful iridescent foliage.

The peacock begonia is characterized by its broad, asymmetric leaves which display a remarkable blue iridescence under certain lighting conditions. This iridescence is not only aesthetically pleasing but also a subject of scientific interest. The leaves appear typically green under low light but reflect a vivid blue metallic color when viewed from different angles, particularly under bright, indirect light. This optical phenomenon is due to the crystalline structure of precisely stacked photosynthetic structures called thylakoids within the chloroplasts of cells at the leaf surface. These scatter light in blue or green wavelengths, much like the way tiny filaments in iridescent peacock feathers do, hence its common name!
