The female parent of 'Balpepin' is the proprietary breeding selection designated 2445-1 and the male parent is the proprietary breeding selection designated 2329-4-3. The initial selection was made in February 2007 based on unique bicoloured flowers. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: Trials for 'Balpepin' were conducted in a polyhouse during the spring of 2011 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 May 9, 2011. Observations and measurements were taken from 10 plants of each variety on June 8, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
