'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.
