Origin & Breeding History: The variety 'Sunparakama' originated from a controlled pollination made at Higashiomi-shi, Shiga-ken, Japan in 2004. The female parent was a proprietary variety designated 'M38-1' and the male parent was a proprietary variety designated 'MH-1'. Seeds from the cross were germinated and grown to maturity. One plant was selected in 2005, propagated by cuttings and grown in pots. A trial was carried out from April to November, 2006. As a result it was concluded that this plant was distinguishable from any other varieties and uniform and stable in its characteristics.

Tests & Trials: Trials for 'Sunparakama' 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 4.4 litre pots on April 26, 2012. Observations and measurements were taken from 10 plants of each variety on July 18, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
