The Stephania erecta is a very special plant. It is also called the 'holy potatoe'.
It belongs to the genus of flowering plants (Menispermaceae) and originally grows in Thailand and Australia - there it wraps itself around trees. It usually grows in peaty soil and likes heat and high humidity, but not too much sun.
This special plant is sent to you in the form of a tuber and can be germinated in a glass jar. You can find more information about this process in this film.
