Origin & Breeding History: The variety 'Cardarpur' originated from a cross made in August 2001 in Enkhuizen, The Netherlands. The female parent was 'B0977-10' and the male parent was 'D1462-2'. A plant was selected from the resulting progeny in May 2002, based on criteria for earliness, flower colour and plant habit.

Tests & Trials: The trials for 'Cardarpur' were conducted in a polyhouse during the spring/summer of 2007, in St. Thomas, Ontario. The trials consisted of a total of 15 plants of the candidate and reference varieties. All plants were grown from rooted cuttings, transplanted into 11.5 cm pots on May 4, 2007. Observations and measurements were taken from 10 plants of each variety on June 25, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
