Origin & Breeding History: 'Evipo024' originated from a cross made in 1997 between 'Burma Star' and 'H.F. Young'. Seed was planted in December 1997 and germinated during the winter and early spring. In the summer of 1998, 'Evipo024' was selected in the greenhouse at Guernsey, Channel Islands, United Kingdom. Selection criteria included compact growth habit, sepal colour, lasting quality as a cut flower, early flowering, suitability to garden situations and container production and very long growing season.

Tests & Trials: 'Evipo024' 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.
