Origin & Breeding History: 'Dekampera' 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 April 2008 between the proprietary seedling designated '41209' as the female parent, and the proprietary seedling designated '06.55556.02' as the male parent. 'Dekampera' was selected from the resultant progeny in November 2008 based on its numerous flower heads per stem, good plant vigour, and good flowering response time. Asexual reproduction of 'Dekampera' was first conducted in December 2008.

Tests & Trials: The detailed description of 'Dekampera' is based on the UPOV report of Technical Examination, application number 2010/2831, 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 2011. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
