Origin & Breeding History: 'PTW1300101' originated from a controlled cross conducted by the breeder, Peter van de Pol, in Twello, Netherlands in July 2011. The cross occurred between two proprietary breeding selections, 'PTW-1200102S' as the female parent variety and 'PTW-1100601S' as the male parent variety. From the resulting progeny, 'PTW1300101' was selected as a unique seedling in July 2012 in Twello for its compact plant growth habit, abundant flowering, shelf life and outdoor performance. Asexual reproduction of 'PTW1300101' was initially conducted by cuttings in January 2013 in Twello, Netherlands.

Tests & Trials: The detailed description of 'PTW1300101' is based on the UPOV report of Technical Examination, application number 2017/2242, 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 2018. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
