This is a new species to cultivation as of 2019 and has yet to be formally named or identified. The red stems and glaucous maroon leaves create a very striking appearance. I have had it in my collection less than a year, so cannot say for sure how large it gets, but I am guessing it stays under 10″. It is a slower species that I have been growing exclusively on moist sphagnum in terrarium conditions. Like many Begonias from this region, it is not fond of standing water on its leaves.
