Begonia vankerckhovenii

This free-flowering Begonia is wonderfully suited for terrariums and is resilient to melting.  The leaves only reach about 1 inch and are delicately serrated with red edges.  The stems are pale and delicate, and very long for the overall size of the plant (not more than 7? tall).  Flowers occur often and are small and cute, and petals are almost circular.
