Origin & Breeding History: The variety 'Sunasahowa' originated from the self-pollination of a proprietary Asarina variety designated 'AS6', conducted in August 2007 in Shiga, Japan. Seeds from the above stated pollination were germinated and grown to maturity. In December 2008, one plant was selected by the inventor in view of its growth habit, flower size and flower colour. The selected plant was propagated by cuttings and grown in a pot trial from April to October 2009. The botanical characteristics of that plant were then examined. As a result, it was concluded that this Asarina plant was distinguishable from any other varieties, and uniform and stable in its characteristics.

Tests & Trials: Trials for 'Sunasahowa' were conducted in a polyhouse during the summer of 2012 in St. Thomas, Ontario. The trial included a total of 20 plants of the candidate variety and 10 plants of the reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots. Observations and measurements were taken from 10 plants of each variety on August 29, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
