Origin & Breeding History: 'Evipo023' originated from a cross made in 1998 between 'Mrs George Jackman' and 'H.F. Young'. Seed was planted in December 1998 and germinated during the winter and early spring. In the spring of 1999, 'Evipo023' was selected in the greenhouse at Guernsey, Channel Islands, United Kingdom. Selection criteria included light blue violet flowers with yellow centre, very free flowering, good repeat flowering, compact growth habit, good flowering on young plants and suitability for small container use.

Tests & Trials: 'Evipo023' was tested at St. Thomas, Ontario. Ten bare root liners of both the candidate and reference variety were planted in the field in Fall 2004. Plants were spaced .6 metres apart and trained to grow along a trellis. Observations and measurements were taken from 10 plant parts on June 15, 2006. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
