Dr Anthony Paul in South Africa has posted on Facebook a picture of a 7 petal Canna that he obtained from Kerala in India, called Canna ‘Yellow Cart Wheel’. The name seems most appropriate for this canna revelation, which has 3 inner petals and 4 outer petals.
The inner petals are the sexual petals and I, for one, am curious to know more about how they are formed, and if they are sterile or whether we can look forward to offspring in due course.
