Origin & Breeding History: 'Royal Pearlz' was bred and developed by the breeders, Nicolaas D.M. Steur and Elly Bak, employees of Corn. Bak B.V. in Assendelft, Netherlands. It originated from a controlled cross conducted in September 2008 between two numbered proprietary selections. Seedlings were selected in April 2010 from the resulting progeny based on their flower colour, number of inflorescences per plant, plant size, leaf size, and plant growth characteristics. 'Royal Pearlz' was selected for commercialization in January 2012 and first propagated using asexual reproduction by cuttings in May 2012, in Assendelft, Netherlands.

Tests & Trials: The detailed description of 'Royal Pearlz' is based on the UPOV report of Technical Examination, application number 2012/2636, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by Naktuinbouw in Roelofarendsveen, Netherlands, in 2013. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
