Origin & Breeding History: The variety 'Calpribul' originated from a cross pollination conducted in Enkhuizen, Netherlands in May 2005. The female parent was a proprietary seedling with light blue flowers, designated G0332-1 and the male parent was a proprietary seedling with dark violet flowers, designated D4809-1. The resultant seed was collected and sown in a greenhouse in Enkhuizen in February 2006. A single plant was selected from the progeny in May 2006, based on criteria for trailing growth habit, plant vigour, flower colour, flower size, early flowering and pH tolerance.

Tests & Trials: Trials for 'Calpribul' were conducted in a polyhouse during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 12, 2011. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 4, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
