Origin & Breeding History: 'HS Kiss' was developed by the breeder at the nursery of Fa. Gebr. Verwer in Lisse, The Netherlands. The variety originated from an open pollinated cross between two unidentified Dahlia plants. The cross was conducted in 1999. A single seedling was selected in 2000, based on criteria for flower colour, plant habit, dark foliage and self-cleaning flowers.

Tests & Trials: The tests and trials for 'HS Kiss' were conducted in a polyhouse during the summer of 2006 in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and 10 plants of the reference variety. Plants of the candidate were grown from rooted cuttings, planted in 15 cm pots on May 24, 2006. Plants of the reference variety were grown from tubers, planted in 15 cm pots on April 25, 2006. Observations and measurements were taken from 10 plants of the candidate variety on July 6, 2006 and the reference variety on June 26, 2006. All colour measurements were made using the RHS Colour Chart 2001.
