Origin & Breeding History: 'Diascot' originated from a controlled cross between the female parent variety 'Divorang' and the male parent designated 'E0210-2' which was made in August 2003 by the breeder Har Stemkens, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. 'Diascot' was selected from the resulting progeny in May 2004 based on its plant form, flower colour and flowering time. Asexual reproduction by cuttings was first conducted in July 2004 in Enkhuizen, The Netherlands.

Tests & Trials: Trials for 'Diascot' were conducted in a polyhouse during the spring of 2008 at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 11.5 cm pots on March 18, 2008. Observations and measurements were taken from 10 plants or parts of plants of each variety on May 12, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
