Origin & Breeding History: 'Butterfly Blue' originated from a controlled cross between the seedling E55 as the female parent and the seedling E35 as the male parent. The cross was made by the breeder, Henricus G.J. van der Knaap, of Kwekerij Mariënoord B.V., Honselersdijk, The Netherlands in July 2000. 'Butterfly Blue' was selected in 2001 based on its double flowers, flower colour, flower shape and leaf colour. Asexual reproduction by vegetative leaf cuttings was first conducted in April 2001 in Honselersdijk, The Netherlands.

Tests & Trials: The detailed description is based on the UPOV (International Union for the Protection of New Varieties of Plants) report of Technical Examination, Community Plant Variety Office reference number 2002/1098, grant number 13958, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the Bundessortenamt in Hannover, Germany, in 2004.
