Origin & Breeding History: 'Kiecawit' originated from the cross of 'Carillion' with an unnamed seedling in Venhuizen, The Netherlands in 2000. The F1 seedlings were grown out and backcrossed to 'Carillion' in 2001. The line was designated #2754 and in 2002, clone #1 was selected as the new variety. Initial selection criteria were plant habit, flower colour, and flower size. Additional selection criteria for vigour and health, reliable propagation and cutting stability were subsequently used to select the new variety.

Tests & Trials: Tests and trials for 'Kiecawit' were conducted in a polyhouse in Oxford Station, Ontario during the summer of 2006. The trial consisted of 15 plants per variety, grown in 10cm pots and spaced approximately 25 cm apart in the polyhouse. Measured characteristics were based on ten measurements. All colour observations were made using the RHS Colour Chart 2001.
