Origin & Breeding History: 'HR 01' originated from a hybrid cross conducted by the breeder H.M. Ruiter in Roelofarendsveen, Netherlands. The cross was made in May 1980 between the variety 'Duchess De Nemour' as the female parent, and variety 'Sarah Bernhardt' as the male parent. In May 1986, 'HR 01' was selected as a single plant from the resulting progeny based on its flower colour, flower size and flower fragrance. 'HR 01' was first propagated by division in 1987 in Roelofarendsveen, Netherlands.

Tests & Trials: The detailed description of 'HR 01' is based on the UPOV report of Technical Examination, application number 2011/1481, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the Naktuinbouw in Roelofarendsveen, Netherlands in 2012.
