Origin & Breeding History: 'Kingscablin' originated from a cross between the female parent a proprietary Scaevola aemula breeding selection designated 04/128d and the male parent the Scaevola aemula variety 'Scawihatis' (Whirlwind White). The cross was conducted on March 17, 2006 at Botanic Garden and Parks Authority in Australia, as part of a controlled breeding program. The initial selection of 'Kingscablin' was made in September 2006 based on flowering time and growth habit. Asexual reproduction since that time has been through the use of vegetative cuttings.

Tests & Trials: Trials for 'Kingscablin' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on May 19, 2010. Observations and measurements were taken from 10 plants of each variety on July 10, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
