Origin & Breeding History: 'Hachdon' originated from a controlled cross pollination conducted by the breeder in the summer of 2003 in Barmstedt, Germany. The cross was conducted between the female parent variety Potentilla fruticosa 'Annette' and the male parent variety Potentilla fruticosa 'Orangeschimmer'. The new Potentilla variety 'Hachdon' was selected as a single plant in July 2006 based on its plant habit, flowering characteristics (including colour) and resistance to powdery mildew. Asexual reproduction of 'Hachdon' was first conducted in July 2006 by softwood cuttings in Barmstedt, Germany.
Tests & Trials: The detailed description of 'Hachdon' is based on the UPOV report of Technical Examination, application number 20140006, 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 2015. The colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
