Can you spot the odd one out :^)..
There are several red clones of Edgeworthia in the trade, the two most common being 'Akabana' & 'Red Dragon' We have owned them both but can't say if they are different from each other or not! Edgeworthia chrysantha 'Akabana' is more commonly labelled as 'Akebono' but apparently this is an incorrect name.
Several years ago I proudly showed off our red flowering Edgeworthia to a visiting friend from Japan. He wasn't overly impressed saying "the red ones die easily". This turned out to be the case while we have never lost a yellow flowering cultivar we have had to replace the red several times!
