Origin & Breeding History: 'White Profusion' originated from a cross conducted by the breeder on June 11, 2014 at a nursery in Zeeland, Michigan, USA. The cross was made between the female parent, an unreleased proprietary variety identified as 12-60-3 and an unknown male parent. The new plant was evaluated and selected in July of 2016 based on plant habit, flower characteristics and disease resistance. Asexual propagation by basal stem cuttings began in July of 2016 in Zeeland, Michigan, USA.

Tests & Trials: The comparative trial for 'White Profusion' was conducted during the summer of 2022 at Variety Rights Management in Oxford Station, Ontario. The trial consisted of 10 plants each of the candidate and reference variety, each individually grown in 16 cm pots. Pots were spaced approximately 45 cm apart. Observations and measurements were taken from 10 plants or parts of 10 plants of each variety. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
