This medium sized Begonia reaches 6-8″ tall in a short amount of time.  The flowers are showy and yellow, and the leaves are edged with bright red.  It is from Africa, but I cannot seem to find out specifically where from.

Meant to get a picture, but this plant is enormous- at least 6 plants in the pot that can easily be divided into decent sized 2″ plants.  It’s currently in a 4″ pot and could be potted up.
