Origin & Breeding History: 'Rap Viotwo' was developed by the breeder Mitchell Hanes, an employee of Goldsmith Seeds, Inc., Gilroy, California, U.S.A. The new variety originated from a cross between the female parent '1281-1', a proprietary line with deep blue coloured flowers, and the male parent 'Lan Depur'. A plant was selected from the resulting progeny in 2002, based on criteria for flower colour and form and plant habit.

Tests & Trials: The tests and trials for 'Rap Viotwo' were conducted in a polyhouse during the spring and summer of 2006, at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 10 cm pots on April 18, 2006. Observations and measurements were taken from 10 plants of each variety on June 17 to 19, 2006. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
