Origin & Breeding History: The variety 'Dala Depsam' originated from a cross made in June 2005 in Andijk, the Netherlands. The female parent was an orange flowered proprietary seedling, designated DS05-115-1 and the male parent was a deep salmon coloured proprietary seedling, designated DS05-103-4. The resultant seed was sown in a greenhouse in October 2005 in Andijk. In January 2006, a single plant was selected from the progeny, based on criteria for flower colour, early flowering and tolerance to heat in outdoor trials.

Tests & Trials: Trials for 'Dala Depsam' were conducted in a polyhouse during the spring of 2011 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 19, 2011. Observations and measurements were taken from 10 plants of each variety on May 24, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
