Origin & Breeding History: 'SAKMEC002' was developed by the breeder, Dr. Julian Greppi, an employee of the Instituto de Floricultura in Buenos Aires, Argentina. It originated from a hybridization conducted in October 2008 between a proprietary Mecardonia procumbens var. tenella line designated 'AM5-264' as the female parent, and a proprietary Mecardonia procumbens var. flagellaris line designated '05-25'. The seed resulting from this cross was collected and sown in a greenhouse in March 2009. The resultant seedlings were transplanted in a field trial where they were evaluated during the spring and summer of 2009 and 2010. In June 2010, the breeder selected one plant based on its yellow flower colour, large flower size, and compact plant growth habit, and gave it the experimental designation 'G2010-37'. In late September 2010, once it was established that the distinct characteristics of 'G2010-37' were stable; this selection was named 'SAKMEC002'.

Tests & Trials: The PBR comparative trial of 'SAKMEC002' was conducted in a polyhouse during the spring of 2014 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm diameter pots on April 28, 2014. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 4, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
