Origin & Breeding History: 'Evipo039' originated from a naturally occurring mutation on a branch of 'Evipo038' in 2002, in Guernsey, England. The mutation was evaluated under controlled conditions and propagated from vegetative cuttings during the summer of 2002. The objective of this hybridization was to create a new and distinct variety for commercial glasshouse and nursery culture. The variety was selected for its profuse light purple flowers with distinct center, long flowering season, reliable flowering and propagation and suitability to container culture in nursery.

Tests & Trials: Trials for 'Evipo039' were conducted during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 8 plants of the candidate variety and 5 plants of the reference variety. All plants were grown from bare-rooted plants grown in 4.4 litre containers and transplanted in the field in August 2009. Observations and measurements were taken from 10 plant parts on July 28, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
