Origin & Breeding History: 'Raspberry Ruffles' originated from a cross and recurrent selection conducted by the breeder, Hans Hansen, in Zeeland, Michigan, USA, in the spring/summer of 2012. The cross was made between the female parent variety 'WP Passion' and the male parent variety 'Fancy Knickers'. Initial selection of the new variety was made during the summer of 2013 based on flower colour and growth habit. Asexual propagation of 'Raspberry Ruffles' by shoot tip cuttings first began during in the summer of 2013.

Tests & Trials: The comparative trial for 'Raspberry Ruffles' was conducted outdoors during the summer of 2021 at Variety Rights Management in Oxford Station, Ontario. The trial consisted of 16 plants of 'Raspberry Ruffles' and 20 plants of each of the reference varieties. Plants were grown individually in 16 cm diameter pots positioned approximately 30 cm apart. Observations and measurements were taking on 10 plants or parts of plants. Colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
