PLANT: creeping growth habit

LEAF BLADE: narrow acute apex, no variegation, upper side medium green

SEPAL: no anthocyanin colouration
FLOWER: single, weak degree of lobing on corolla lobes
COROLLA LOBE: truncate apex, one colour on upper side, upper side violet (RHS N82A) when newly opened, lighter violet (RHS N82C) when fully opened with darker violet (RHS N82A) and white (RHS 155B) at transition to corolla tube, ages to light blue violet (RHS 76C) with violet (RHS N82C) at transition to corolla tube, medium to strongly conspicuous veins on upper side, lower side light blue violet (RHS 76A-B)
COROLLA TUBE: inner side light yellow (RHS 4C) with weakly conspicuous veins.

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.
