Origin & Breeding History: 'Balserilla' originated form the cross pollination between the female proprietary breeding selection 224-1op-1 and the male proprietary breeding selection 172-2-3-2 conducted in August 2005, at Santa Paula, California, United States. Selection of 'Balserilla' was made in February 2006 based on flower colour, growth habit and flowering that best matched the 'Serenity' series. Asexual propagation since its selection has been through vegetative cuttings.
Tests & Trials: Trials for 'Balserilla' 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 11 cm pots on March 31, 2009. Observations and measurements were taken from 10 plants of each variety on June 1, 2009, with the exception of 'KLEOE05521' which was measured on June 25, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
