Origin & Breeding History: 'Evipo037' originated from a cross made in the spring of 1999 in Guernsey, England. The resulting seeds were germinated in January 2000 and were evaluated in the summer of that year. 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 dark blue to purple flowers and suitability to container production.

Tests & Trials: Trials for 'Evipo037' were conducted during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 7 plants of the candidate variety and 6 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 of the candidate variety on July 6, 2011, and the reference variety on July 23, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
