The new variety was selected based on branching characteristics, number of flowers, flower size and performance throughout the summer. 'USTUN19603' was first propagated by vegetative cuttings on May 30, 2005 in Bonsall, California, United States.
Tests & Trials: Trials for 'USTUN19603' 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.
