Origin & Breeding History: 'Sil Quirin' arose from a controlled cross between the variety 'Hillscheider Amethyst', characterized by its medium violet flower colour, medium green foliage with weak zonation and semi-upright growth habit, and 'Royal Blue', characterized by its medium-dark purple flower colour, medium green foliage without zonation and semi-upright growth habit. The cross was conducted in Weener, Germany in the summer of 2000. Initial selection was made in June, 2001 based on flower colour, flower shape, flowering maturity and foliage zonation. Since then, asexual propagation has been through vegetative cuttings.

Tests & Trials: The comparative test and trial of 'Sil Quirin' was conducted in a polyhouse during the summer of 2008 at Bioflora Inc. in St. Thomas, Ontario. The trial included 20 plants of each variety. All plants were grown from rooted cuttings transplanted into 30 cm hanging baskets on May 14, 2008. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 17, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
