Origin & Breeding History: 'A4071-1' originated from the hybridization of an unnamed seedling (530-2) with the male parent 'Carmine'. The cross took place in Venhuizen, The Netherlands in 2002. The F1 seedlings were grown out in 2002 and were evaluated for plant habit, flower colour, and flower size. In 2003, the new variety was selected and reliable propagation and cutting stability were used as the final selection criteria for this new variety.

Tests & Trials: Tests and trials for 'A4071-1' 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.
