Origin & Breeding History: 'Bonpripicom' was bred in May 2002 by controlled pollination between proprietary Euphborbia pulcherrima selection #83 as the female parent and an unnamed proprietary selection of Euphorbia cornastra as the male parent, in an isolated area at Bonza Botanicals Pty Limited in Yellow Rock, New South Wales. Seeds from this cross were germinated, grown to maturity, and in August 2003, one plant was selected based on its growth habit and bract colour. The selected plant was propagated by cutting and grown in pots in a greenhouse. A trial was carried out in a controlled environment from 2003 to 2004 during which the botanical characteristics of the plant were examined. It was concluded that this Euphorbia hybrid was distinguishable from any other varieties, and that its characteristics were uniform and stable. It was subsequently named 'Bonpripicom'.
Tests & Trials: The detailed description of 'Bonpripicom' is based on the UPOV report of Technical Examination, application number 2009/0530, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the Department of Horticulture at the University of Aarhus in Aarslev, Denmark, in 2010. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
