The resultant seed was planted in December 1996 and germinated during the winter and early spring. In July 1997, 'Evipo009' was selected in the greenhouse at Guernsey, Channel Islands, United Kingdom. Selection criteria included large white flowers, compact growth habit and red-brown flower centre.

Tests & Trials: 'Evipo009' was tested at St. Thomas, Ontario. Ten bare root liners of both the candidate and reference variety were planted in the field on September 18, 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.
