Origin & Breeding History: 'Diswe' originated from a controlled cross conducted by the breeder Roy Robin van Dijk in De Lier, Netherlands in April 2010. The cross was made between two proprietary selections, the female parent designated '1004' and the male parent designated '1001'. From the resulting progeny, 'Disno' was selected as a single unique plant in April 2012 in De Lier, Netherlands based on its overall plant form and appearance, branch strength, reblooming, disease tolerance and shelf life.
Tests & Trials: The detailed description of 'Diswe' is based on the UPOV report of Technical Examination, application number 20141960, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by Groupe d'Étude et de Contrôle des Variétés et des Semences in Brion, France between February 15, 2015 and December 15, 2016. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
