Origin & Breeding History: 'Evipo020' originated from a cross made in the spring of 1996 between the Clematis viticella variety 'Vinesa Violacea' and an unnamed seedling. The resulting seed was planted in December 1996 and in the spring of 1997, the seedlings were selected at Domarie Vineries Les Sauvagees, in St. Sampsons, Guernsey, Channel Islands, United Kingdom. The objective of this hybridization was to create a new and distinct variety for commercial glasshouse and nursery culture with a long flowering season, purple double blooms, evergreen foliage when protected from frost, good flower longevity and improved continuous flowering.

Tests & Trials: Trials for 'Evipo020' were conducted in a polyhouse during the winter and spring of 2009 at BioFlora Inc. in St. Thomas, Ontario. It included 10 plants of the candidate variety and 6 plants of the reference variety. All plants were grown from bare-rooted plants which were transplanted into 4.4 litre containers on December 16, 2008. Observations and measurements were taken from 10 plants or parts of plants of the candidate variety on May 7, 2009, and 6 plants or 10 parts of 6 plants of the reference varieties on May 25, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
