Origin & Breeding History: 'Peni Vio09' originated from a cross made in July 2005 in Gilroy, California, USA. The female parent was a proprietary seedling, designated 14-1, with violet flowers and the male parent was a proprietary seedling, designated 104-1, with light pink coloured flowers. The resultant seed was sown in a greenhouse in October 2005 and in April 2006, a single plant from the progeny was selected by the breeder based on flower colour, flower quality and compact plant habit.

Tests & Trials: Trials for 'Peni Vio09' were conducted in a poly-house during the summer of 2009 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen plants per variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 21, 2009. Observations and measurements were taken from ten plants of each variety on July 22, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
