Origin & Breeding History: 'Keipunes' originated from a crossing of unnamed breeding lines which was conducted in October 2000 at Katori-shi, Chiba-ken, Japan. In April 2001, 121 seedlings were obtained from that crossing. Those seedlings were grown in pots in a glasshouse and evaluated. In September 2002, one seedling was selected in view of its growth habit, flower size and colour. The selected plant was propagated by cuttings and grown in pots, and included in a trial from April to September 2003. As a result of an examination of botanical characteristics, it was concluded that the variety was distinct from other varieties, and was also uniform and stable. The new variety was named 'Keipunes'.

Tests & Trials: The trials for 'Keipunes' were conducted during the spring of 2007, in a polyhouse in St. Thomas, Ontario. The trials consisted of a total of 15 plants of the candidate and reference varieties. All plants were grown from rooted cuttings planted into 15cm pots on April 24, 2007. Observations and measurements were taken from 10 plants of each variety on June 5, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour chart.
