Origin & Breeding History: 'Pic Rossa' originated from a cross between the female parent '1356-6' and the male parent 'MP 209'. The new Petunia was bred and developed by the breeder Mitchell Hanes in August 2004, in Gilroy, California, United States. The resultant seed from the cross was sown in a greenhouse in February 2005. In May 2005, a single plant from the progeny was selected by the breeder based on flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'Pic Rossa' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 27, 2010. Observations and measurements were taken from 10 plants of each variety on May 27, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
