Origin & Breeding History: 'G6048-1' originated from a controlled self-pollination of the female parent plant identified as 03-64-2 with a mix of pollen from male parents of the same plant. The cross was conducted by the breeders David W. Kerley and Priscila Kerley in August 2003, in Cambridge, United Kingdom. A single seedling was selected from the progeny in May 2004 based on time of maturity, flower colour, plant growth habit and plant stability. Asexual reproducted by cuttings of 'G6048-1' was first conducted in August 2005, in Enkhuizen, The Netherlands.

Tests & Trials: Trials for 'G6048-1' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 30, 2009. Observations and measurements were taken from 10 plants of each variety on May 27, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
