A single plant was selected from the resultant progeny in May 2005 based on growth habit, flower colour and production characteristics.

Tests & Trials: Trials for 'Pic Rossa' were conducted in a polyhouse during the spring of 2012 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 25, 2012. Observations and measurements were taken from 10 plants of each variety on May 25, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
