Origin & Breeding History: 'Sunbelremo' originated from a cross between the female parent 'S39' and the male parent 'YS5' conducted in April 2004 at Higashiomi-shi, Shiga, Japan. The seedlings from the cross were grown in pots in the glasshouse and evaluated. In September 2005, one seedling was selected based on its growth habit, flower size and flower colour. The selected plant was propagated by cuttings and grown in pots. The trial was carried out from April to September 2006 at Higashiomi-shi, Shiga, Japan. The botanical characteristics of that plant were examined and found to be distinguishable from any other varieties. The new Calibrachoa variety was named 'Sunbelremo'.

Tests & Trials: Trials for 'Sunbelremo' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted in to 30 cm hanging baskets on May 21, 2009. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 8, 2009. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
