Origin & Breeding History: 'MACtro' was developed as part of a selective breeding program. It was derived from the open pollination of Canna variety 'Phasion' conducted in 2000 in Auckland, New Zealand. 'MACtro' was selected from the resulting progeny based on the colour variation of the interveinal striping of its leaves.

Tests & Trials: The detailed description of 'MACtro' is based on the UPOV report of Technical Examination, CPVO reference number 20040732, grant number 21407. The trials were conducted by Naktuinbouw in Wageningen, The Netherlands in 2005 to 2007. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
