Origin & Breeding History: 'Sunasashiro' originated from a cross made in May 2002 at Higashiomi-shi, Shiga-ken, Japan. The female parent was a proprietary Asarina hybrid designated 3Asa-1 and the male parent was a proprietary Asarina hybrid designated 2022-S. In January 2003, seedlings from the cross were grown in pots in the greenhouse and evaluated. In September 2003, one seedling was selected for its growth habit, flower size and flower colour. The selected plant was propagated by cuttings and grown in a potted trial in 2004 where the variety was determined to be distinct, uniform and stable.

Tests & Trials: Trials for 'Sunasashiro' were conducted during the spring/summer of 2008 in a polyhouse at BioFlora Inc. in St. Thomas, Ontario. The candidate variety was grown from rooted cuttings while the reference variety was grown from seed. Rooted plants were transplanted into 10 inch baskets with 3 plants per basket on May 14, 2008. The trial contained six baskets of the candidate variety and 5 baskets of the reference variety. Observations and measurements were taken from 10 plants on August 5, 2008. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
