The F1 seedlings were grown out in 1998 where 'Kiedahred' was selected based on improved floral traits, flower diameter, plant vigour and ease of propagation.

Tests & Trials: Trials were conducted during the summer of 2006 in Oxford Station, Ontario. 15 plants of each variety were individually grown in 10cm pots in a polyhouse. Plants were spaced 25cm apart. Observations and measurements were taken on 10 plants of each variety. Colours were determined using the 2001 RHS Colour Chart.
