The initial selection was made in May 2008 based on plant growth habit, flower and vein colour, and flower size. The new variety was first propagated by vegetative tip cuttings in September 2008.
Tests & Trials: Trials for 'Kerivoryvein' were conducted in a polyhouse during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on August 7, 2012. Observations and measurements were taken from 10 plants of each variety on September 14, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
