Origin & Breeding History: 'PSDBH15701' originated from a controlled cross pollination conducted by the breeder, Peter van de Pol, in Twello, Netherlands in August 2013. The cross occurred between two proprietary breeding selections, 'PSDBH1200302S' as the female parent variety and 'PSDB-1300101S' as the male parent variety. From the resulting progeny, 'PSDBH15701' was selected as a unique seedling in July 2014 in Twello for its compact plant growth habit, short branch length, purple flower colour and large white eye. Asexual reproduction of 'PSDBH15701' was initially conducted by cuttings in November 2014 in Twello, Netherlands.

Tests & Trials: The detailed description of 'PSDBH15701' is based on the UPOV report of Technical Examination, application number 2015/2375, purchased from the Community Plant Variety Office in Angers, France. The trial was conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2016. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
