Origin & Breeding History: 'Kasumi' orignated as a whole plant mutation of the variety 'Konatu' discovered in July 2004 in an isolated area at Tsushima, Aichi, Japan. The discovered plant was grown in a trial from July 2007 to August 2008 in a controlled environment. The botanical characteristics of the plant were then examined. As a result, it was concluded that this Bougainvillea plant was distiguishable from any other varieties and named 'Kasumi'.
Tests & Trials: Trials for 'Kasumi' were conducted in a polyhouse during the summer of 2012 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cutttings and transplanted into 15 cm shallow pots on May 2, 2012. Observations and measurements were taken from 10 plants of each variety on June 26, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
