Origin & Breeding History: 'Kakegawa S86' originated from a cross conducted during 2002, in Kakegawa, Japan. The cross was between the female proprietary breeding line 'S-24A-23' and the male proprietary breeding line '1B-69B'. The initial selection of 'Kakegawa S86' was made in 2003 based on its flower colour and growth habit. The variety has been maintained since 2003 through the use of vegetative shoot-tip cuttings.

Tests & Trials: Trials for 'Kakegawa S86' were conducted during the summer of 2007, in a polyhouse, 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 into 30 cm hanging baskets on May 1, 2007. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety (except for plant height where 5 plants were measured) on July 3, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
