Origin & Breeding History: 'Keisurflipinas' was discovered in July 2010 and developed by the breeder, Shunsuke Takeuchi, as part of a breeding program in Katori, Chiba, Japan. It was the result of a naturally occurring whole branch mutation of the variety 'Keisurfpusos'. The new variety 'Keisurflipinas' was selected based on its plant growth habit, plant vigour, branching characteristics, long flowering period, flower colour and abundance, and good garden performance. Asexual reproduction of 'Keisurflipinas' by cuttings was first conducted in July 2010.
Tests & Trials: The comparative trial for 'Keisurflipinas' was conducted in a polyhouse during the summer of 2014 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on June 18, 2014. Observations and measurements were taken from 10 plants or parts of plants of each variety on July 7, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
