Origin & Breeding History: 'Ingbicrewi' was developed by the breeder, M. Sanders, an employee of Syngenta Seeds B.V. in The Netherlands. It originated from a cross made in September of 2000 between the female parent designated 'G585-1' and the male parent designated 'G108-3'. 'Ingbicrewi' was selected from the resulting progeny in September of 2001 based on criteria for good branching, foliage size, flower size and flower colour.

Tests & Trials: The comparative test and trial of 'Ingbicrewi' was conducted in a poly-house during the summer of 2006 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots on May 23-25, 2006. Observations and measurements were taken from 10 plants of each variety on August 11, 2006. All colour determinations were made using the Royal Horticultural Society (RHS) Colour Chart 2001.
