I received my first Raphidophora celatocaulis (pictured right) from Lyndi several months ago. It is such an easy plant to grow because I merely stick it in a pot of soil, lean it against a wall and in no time, the plant will start climbing and producing offshoots! I got the variegated Raphidophora cryptantha (pictured left) from Woon Leng during the recent SGF but it isn't as vigourous as the celatocaulis.
The Raphidophora is a genus in the family Araceae and it consists up to approximately 100 species.
