Origin & Breeding History: 'Suncalho' originated from a controlled pollination of the proprietary variety '2666-1' with the variety '3135-2' conducted in an isolated area from April to November 2006 in Higashiomi, Shiga, Japan. Seeds from the pollination were germinated and grown to maturity. One plant was selected by the breeder in September 2007 based on growth habit, flowering period, flower size, flower type, flower colour as well as resistance to rain, heat, drought and disease. The selected plant was propagated by cuttings and grown in pots. A trial was carried out from April to September 2008 where it was determined that this variety was distinguishable from any other varieties and it was named 'Suncalho'.
Tests & Trials: Trials for 'Suncalho' were conducted in a polyhouse during the summer-fall of 2010 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and 10 cm pots on August 5, 2010. Observations and measurements were taken from 10 plants of each variety on September 25, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
