Origin & Breeding History: 'HORT01' originated from a population of hybrid Rhododendron simsii seedling and was selected in March 2000. The seedlings were created from a hybridization of 'Ambrosiana' and an unknamed proprietary seedling designated '92138' that was conducted in 1998 at Kruishoutem, Belgium. The initial selection of 'HORT01' was based on long lasting flowers and compact growth habit.
Tests & Trials: The detailed description of 'HORT01' is based on the UPOV report of Technical Examination, application number 2009/0901, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the Bundessortenamt in Hannover, Germany, in 2010. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
