Origin & Breeding History: 'Pheni Pinka' was developed by the breeder, Jason Jandrew, an employee of Goldsmith Seeds in California, U.S.A. as part of a planned pedigree breeding program. It originated from a cross made on August 2, 2002 between the proprietary female parent line designated '104-3' with blush pink flowers, and the proprietary male parent line designated '105-1' with pink flowers. 'Pheni Pinka' was selected on May 3, 2003 based on its plant growth habit, flower colour and flower form.

Tests & Trials: The comparative test and trial of 'Pheni Pinka' was conducted in a polyhouse during the summer of 2006 at Bioflora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on March 21, 2006 . Observations and measurements were taken from 10 plants of each variety on July 7, 2006. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
