Begonia ningmingensis ‘Dark form’

There are a few forms of B.ningmingensis, and they all look drastically different. The dark form seems to be an easy keeper, fast-growing, and a regular bloomer.  Leaves are a velvety brown, with newer growth being greener.  It occurs in China and grows to about 10″. It will often grow very close to the substrate, especially at first, forming a little tented area on the substrate.
