[edit] Taxonomy
In the last three decades of the 20th century, Canna species have been categorised by two different taxonomists, Professor Paul Maas (and his wife Dr. Hiltje Maas) from Holland and Dr. Nobuyuki Tanaka from Japan. Inevitably, there are differences in their categorisations, however, they are both in agreement that this is a distinct and separate species.
