Begonia sp. blue metallic

This species resembles kapaushuluensis, but has more corrugated leaves that aren’t quite as shiny (more of a ‘matte’ patina). It’s highly iridescent and flowers readily. Abaxial leaf surfaces and blooms are a bright pinkish-red. I have only seen this species offered by one other seller in the US. The last photo are representative of the plants available. They are well rooted and shipped meticulously in their pots.
