Silverleafed princess flower, Colombia
Found in the gardens of the Montezuma lodge, Colombia. Photographed at night.
Our guide pointed it out as family Melastomataceae. I further narrowed it down based on this reference:
https://en.wikipedia.org/wiki/Tibouchina_heteromalla
In particular the flower photo on Wikipedia seems a solid match, and the fact that is cultivated across the world. I could be wrong though.
''Tibouchina heteromalla'', known by the common name silverleafed princess flower in English is a species of evergreen flowering plant in the genus ''Tibouchina'' of the family Melastomataceae. It is native to Brazil.
