Origin & Breeding History: 'Sunphlorozu' originated from a naturally occurring bud mutation of '9Ph-17a' discovered in June 2005, at Higashiomi-shi, Shiga-ken, Japan. The discovered shoot was propagated by cuttings, grown in pots in the glasshouse and evaluated. One plant was selected for the stability of its characteristics and named 'Sunphlorozu'.
Tests & Trials: Trials for 'Sunphlorozu' 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.
