Origin & Breeding History: 'Sunsenehobume' originated from a controlled cross conducted in March 2008 at the Omi R&D Center of Suntory Flowers Ltd., in Higashiomi-shi, Shiga, Japan. The cross was made between the female parent '07-21' and the male parent '07-18'. The seedlings were collected from the cross and evaluated for growth habit, number of flowers and size of flowers. In February 2010 one seedling was selected based on its growth habit and flower colour. The new variety was propagated by cuttings and evaluated from October 2010 to March 2011.

Tests & Trials: The comparative trial for 'Sunsenehobume' was conducted in a polyhouse during the spring of 2016 at Bioflora Inc. in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 3.8 litre pots on April 15, 2016. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 16, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
