Origin & Breeding History: The variety 'Intraiwhitwo' originated from a hybrid cross, made in Heidesheim, Germany in 2007. The female parent was a white flowered proprietary seedling, designated as N 05 82-1 and the male parent was a yellow flowered proprietary seedling, designated as N 04 65-50. The new variety was selected from the resultant progeny in 2008, based on criteria for plant growth habit, flower colour and size, excellent branching and strong plant vigour.

Tests & Trials: Trials for 'Intraiwhitwo' were conducted in a polyhouse during the spring of 2011 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 11 cm pots on April 19, 2011. Observations and measurements were taken from 10 plants of each variety on May 17, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
