Origin & Breeding History: 'Gipi Whit' was discovered and developed by the breeder Robert Pierce, an employee of Goldsmith Seeds, Inc., in Gilroy, California. Commercial open pollinated seed of the Achillea variety 'The Pearl' was sown in April 2003 and all germinated seedlings were planted in the field. A single plant designated 3-4 was selected in August 2003 based on compact growth habit, excellent flowering, and better branching. The new variety was asexually reproduced from the selected plant.

Tests & Trials: PBR trials were conducted in a polyhouse during the spring of 2007 in St. Thomas, Ontario. Trials included 15 plants of the candidate and reference variety. Plants were grown from rooted cuttings, transplanted into 11.5 cm pots on May 9, 2007. Observations and measurements were taken from 10 plants of each variety on July 9, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
