Begonia sutherlandii going into dormancy.
Bulbils forming on the leaf axils.

Begonia sutherlandii in its prime.
I've just come across a post on a gardeners chat site from someone who calls themselves 'Bigoniac'. I can sympathize with this condition as I could very easily become manic about this family of plants myself. However, I have been unusually disciplined, deciding that I just don't have the space to go whole hog on another plant collecting jag. I have allowed myself only one and that is Begonia sutherlandii. In its prime it has fresh pale green leaves with red veins and stems, it blooms most of the summer with lovely pale orange flowers.
As it approaches Autumn, as if sensing the need to survive, it produces fascinating little bulbils at the juncture of the leaves and stems. This year they seem to be particularly well developed, having formed leaves and roots on the tiny bulbs.
