Origin & Breeding History: The variety 'Bokraspiwi' originated from an open pollination that occurred in the summer of 2000 in Boskoop, Netherlands. The female parent was a proprietary seedling designated 93115 and the male parent was unknown. In June 2007, the new variety was selected as a single seedling based on criteria for compact and dense growth habit, purple-black leaf colour and purple flower colour. Asexual reproduction of the new variety was first conducted by softwood cuttings in the summer of 2007 in Boskoop, Netherlands.

Tests & Trials: Trials for 'Bokraspiwi' were conducted in an outdoor container trial during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and reference variety. Plants were grown from 11 cm rooted liners and planted into 8.8 litre containers on July 7, 2011. The plants were overwintered in a polyhouse and moved outdoors in late April 2012. Early observations and measurements were taken from 10 plants of each variety on August 15, 2012. Flower characteristics were observed in September 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
