There are a few forms of B.ningmingensis, and they all look drastically different. The dark form seems to be very hardy and fast growing, and it flowers all the time. Leaves are a velvety dark green, with newer growth being lighter green. It is a newer species from China that grows to about 10″. It will often grow very close to the substrate, especially at first, forming a little tented area on the substrate.
A native of Southern China and Indo-China, this Begonia can grow to over a foot tall, with leaves staying around 4-5″. It is very easy to keep small in the terrarium however, and seems to be a slower growing, albeit not too difficult, species. The stems are a striking red and the white spotting on foliage becomes even more prominent as the plant matures.
