Origin & Breeding History: 'NPCW12198' originated from a cross between the female parent variety 'Christmas Season' and an unknown male parent variety in November 2004 in Nairobi, Kenya. Seedlings from the cross were selected in Stuttgart, Germany in October 2005 based on foliage quality, bract colour, bract quality and plant vigour.

Tests & Trials: The trial for 'NPCW12198' was conducted in 2013 at Schenck's 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.
