Origin & Breeding History: 'Petouch' originated from a controlled pollination of the female petunia plant identified as Y0892 with pollen from another petunia plant identified as A1057. The new variety was bred and developed by the breeder D. van Keinwee, in Enkhuizen, The Netherlands, in July 2001. A single seedling was selected in May 2002, in Enkhuizen based on time of maturity, flower colour, plant growth habit and plant stability. Asexual reproduction by cuttings of the new variety was first conducted in August 2002, in Enkhuizen, The Netherlands.
Tests & Trials: Trials for 'Petouch' were conducted in a polyhouse during the spring of 2009 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 30, 2009. Observations and measurements were taken from 10 plants of each variety on May 27, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
