The female parent was the proprietary dahlia selection '1151', characterized by its white flower colour and upright growth habit, with the male parent being 'Dapasuje' (Jenny) characterized by its orange-red flower colour and compact growth habit. Initial selection was made on May 1, 2003 based on flower colour, and branching growth habit.

Tests & Trials: Trials were conducted in a polyhouse in the spring/summer of 2006 in St. Thomas, Ontario. The trial included 15 plants of the candidate and reference varieties each individually grown in 15cm pots. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 RHS colour chart.
