This popular Begonia hails from Malaysia and is one of the easier species to grow.  Unfortunately, due to overcollection, it is thought to be extinct in the wild.  It’s brightly colored foliage and small growth make it ideal for terrariums.  It does not seem to be one prone to melting and the leaves are very sturdy, making a nice perch for larger frogs and geckos.

The last photo is representative of the plants available. They are well rooted and shipped meticulously in their pots.
