Origin & Breeding History: 'NPCW12202' originated from a cross conducted in November 2006 in Nairobi, Kenya between 'Christmas Season' as the female parent and the variety designated 'P212' as the male parent. Seedlings from the cross were selected in Stuttgart, Germany in October 2007 based on foliage quality, bract colour, bract quality and plant vigour. Further evaluations were conducted in greenhouse trials from August 2008 to December 2011. 'NPCW12202' was selected for commercialization in December 2010.

Tests & Trials: The trial for 'NPCW12202' was conducted in 2013 at Colonial Greenhouses in St. Catharines, Ontario. The trial included 25 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on July 27, 2013. Pots were spaced 30 cm apart from the pot centre. Observations and measurements were taken from 10 plants of each variety on December 11, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
