Origin & Breeding History: 'Balserimwhi' originated from the cross of the proprietary breeding selection '33056-2', as the female parent, with another proprietary seedling selection, '33056-1', as the male parent. The cross was conducted in April 2003 in Santa Paula, California, USA. The initial selection was made in December 2003. Asexual propagation since that time has been through the use of vegetative cuttings. Selection criteria included plant vigour and uniform growth habit.

Tests & Trials: The trials for 'Balserimwhi' 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.
