Origin & Breeding History: 'GRUHEL02' originated from a cross between two unnamed proprietary seedlings of Helleborus niger conducted in Boskoop, Netherlands in December of 2000. The new variety 'GRUHEL02' was selected between November and December of 2013 based on growth habit, flower size, glossiness of foliage and heat tolerance.

Tests & Trials: The detailed description of 'GRUHEL02' is based on the UPOV report of Technical Examination, reference number 2017/3134, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by Naktuinbouw in Roelofarendsveen, Netherlands, from 2018 to 2019. Colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
