Origin & Breeding History: 'Sunphlorai' originated from a cross of the female parent '2Ph-54a' and the male parent '2Ph54b' conducted in June 2002, at Higashiomi-shi, Shiga-ken, Japan. The seedlings obtained from the cross were grown in pots in a glasshouse and evaluated. In May 2004, one seedling was selected based on its growth habit, flower size and flower colour. This new phlox variety was named 'Sunphlorai'.

Tests & Trials: Trials for 'Sunphlorai' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 2, 2009. Observations and measurements were taken from 10 plants of each variety on May 28, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
