The female parent was the variety 'Christmas Star' and the male parent was unknown. Seedlings were selected from the cross in 2005 for criteria based on bract size, bract colour, bract shape, leaf quality and branching characteristics. One of these seedlings was designated 'NPCW08153' and was further evaluated in 2006 for bract shape, plant vigour and postharvest characteristics.

Tests & Trials: Trials for 'NPCW08153' were conducted in a greenhouse in St. Catharines, Ontario . The trial included a total of 25 plants each of the candidate variety and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on August 10, 2010. Observations and measurements were taken from 10 plants of each variety on December 1, 2010. All colour determinations were made using the 2007 Royal Horticultural Society Colour Chart.
