Origin & Breeding History: 'Deklightning' was bred and developed by the breeder, Cornelis W. Dekker, in Hensbroek, Netherlands, as part of a planned breeding program. It originated from a hybrid cross conducted in October 2008 between the proprietary seedling designated '07.63564.01' as the female parent, and the proprietary seedling designated '07.63967.01' as the male parent. 'Deklightning' was selected from the resultant progeny in April 2009 based on its purple flower colour, spatulate type ray florets, good response time, and good vase life. Asexual reproduction of 'Deklightning' was first conducted in May 2009.

Tests & Trials: The detailed description of 'Deklightning' is based on the UPOV report of Technical Examination, application number 2011/1853, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom, in 2012. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
