The caudex forms under
ground, and I have not tried to rice it.
This member of the Begoniaceae family was given this name by
Alphonse Louis Pierre Pyramus de Candolle in 1859. It is found
in Boilivia and Argentina, growing in a well drained soil or simply
quite some water and only little or no sun. The caudex can grow to
centimetres in diameter, the entire plant to fifty centimetres in
flowers are bright red.
