Origin & Breeding History: 'Peni Pina09' 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 in July 2005 between the proprietary female parent line designated '104-1' with apple blossom coloured flowers, and the proprietary male parent line designated '125-3' with white with red-throat coloured flowers. 'Peni Pina09' was selected in April 2006 based on plant growth habit and flower colour and quality.

Tests & Trials: The comparative test and trial of 'Peni Pina09' was conducted in a polyhouse during the spring-summer of 2008 at Bioflora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 20 cm pots on May 15, 2008 . Observations and measurements were taken from 10 plants of each variety on July 18, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
