A pollen mixture from the breeding group 7K-85 was used to pollinate all plants within group 7K-34. 'Fiworewhi' was selected in June 1998 based on its compact growth habit, bi-coloured flowers and good outdoor performance.

Tests & Trials: Tests and trials for 'Fiworewhi' were conducted in St. Thomas, Ontario in the summer of 2003. The plants were grown from rooted cuttings transplanted into 15cm pots in week 16. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten plant measurements.
