Origin & Breeding History: 'Fisrix Dered' originated from a cross conducted in July 2003, between the female parent 'Moulin Rouge' and the male parent 'My Fair Lady'. The new Mandevilla was developed by the breeder Birgit Hofmann, in Hillscheid, Germany as part of a planned breeding program. The resultant seed from the cross was sown in a greenhouse in October 2003. In September 2004, the breeder selected a single plant from the progeny based on flower colour.

Tests & Trials: The detailed description of 'Fisrix Dered' is based on the UPOV report of Technical Examination, application number 2006/2661, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by Naktuinbouw in Wageningen, The Netherlands in 2008. Colour determinations were made using the Royal Horticultural Society (RHS) Colour Chart.
