Origin & Breeding History: 'Petrosena' originated from a controlled cross made in 2000 in Enkhuizen, The Netherlands, between the female parent, 'A998-1' and the male parent 'Y942-4'. A plant was selected from the resultant progeny of the cross in 2001, based on flower characteristics and plant habit. Asexual reproduction by vegetative cuttings was first conducted in August, 2001 in Enkhuizen, The Netherlands.
Tests & Trials: The tests and trials for 'Petrosena' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario in the spring of 2006. The trials included 15 plants of each variety. Rooted cuttings were transplanted into six inch pots on April 17, 2006. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
