Origin & Breeding History: 'Sil Linus' originated from a cross conducted during the summer of 2001 at Silze GmbH & Co. KG, Weener, Germany, as part of a controlled breeding program. The female parent was the variety 'Kitty', characterized by its light pink violet flower colour with small red coloured spots, dark green foliage colour with no zonation, and compact and upright growth habit. The male parent was the variety 'Lady', characterized by its light pink flower colour with medium red coloured spots, dark green foliage colour with no zonation, and compact and upright growth habit. The initial selection was made on June 2002. The selection criteria were flower form, flower colour and colour pattern.

Tests & Trials: Trials for 'Sil Linus' were conducted in a polyhouse in St. Thomas, Ontario, during the summer of 2008. The trials consisted of 15 plants of each variety. All plants were grown from rooted cuttings, transplanted into 15 cm pots on May 20, 2008. Observations and measurements were taken from 10 plants of each variety on July 19, 2008. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
