Origin & Breeding History: 'Sunmandecrikin' originated from a cross made at Higashiomi-shi, Shiga-ken, Japan in June 2001. The female parent was the variety 'Sunmandeho' and the male parent was the breeding line M38-1. Seedlings obtained from the cross were grown in the glasshouse and evaluated in 2002. One seedling was selected based on its growth habit and flower colour. The selected plant was propagated vegetatively and grown in a pot trial from May to October 2004 in Japan.

Tests & Trials: The tests and trials for 'Sunmandecrikin' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario in the fall of 2006. The trials included 15 plants of each variety. Rooted cuttings were transplanted into 20 cm pots on May 26, 2006. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
