Origin & Breeding History: 'Dekskye' was bred and developed as part of a planned breeding program by the breeder, Cornelius W. Dekker, in Hensbroek, Netherlands. It originated from a hybrid cross conducted in February 2008 between the female parent, proprietary seeding number '41048', and the male parent, proprietary seedling number '04.42289.03'. 'Dekskye' was selected from the resultant progeny in October 2008 based on its good branching and stem strength, flower colour and type, and good vase life.

Tests & Trials: The detailed description of 'Dekskye' is based on the UPOV report of Technical Examination, application number 2010/0386, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom, in 2010. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
