Origin & Breeding History: 'NPCW10158' originated from a cross between the female parent designated P 359 and the male parent variety 'Christmas Star'. The cross was conducted in November 2004 in Stuttgart and seedlings were selected in October 2005 based on bract shape, bract size, bract colour, stem quality and leave quality. A greenhouse trial was conducted in the fall of 2006 and seedlings were evaluated for the above criteria and for plant vigour, growth habit and response time. One of these seedlings was designated 'NPCW10158' and was selected for commercialization in November 2008.

Tests & Trials: The detailed description of 'NPCW10158' is based on the UPOV report of Technical Examination, application number 2010/0053, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the University of Aarhus in Aarslev, Denmark, in 2011. Colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
