Origin & Breeding History: 'Tra Tercot' originated from the cross using a proprietary seedling, 'OZ-185-1', as the female parent, with another proprietary seedling, 'OY-81-2', as the male parent, conducted in June 1999 in Andijk, the Netherlands. The resultant seed was sown in the greenhouse in August 2003. In January 2004, a single plant from the progeny was selected for flower quality and colour, and compact growth habit.

Tests & Trials: The trials for 'Tra Tercot' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2007. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
