Origin & Breeding History: 'Ingmulwhi' 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 1999, between the female parent designated F25-2 and the male parent designated F25-1. 'Ingmulwhi' was selected from the resulting progeny in September of 2000, based on criteria for good branching, foliage size, flower size, number of flowers and colour.

Tests & Trials: The comparative test and trial of 'Ingmulwhi' 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 October 11, 2006. All colour determinations were made using the Royal Horticultural Society (RHS) Colour Chart 2001.
