Origin & Breeding History: 'Sunjodiropi' originated from a controlled pollination of female parent 'd1001' and male parent 'd76' conducted on June 7, 2008 at Penhow Nurseries in Carrow Hill, St. Brides Netherwent, United Kingdom. Seeds were germinated and grown to maturity. On August 20, 2008, one plant was selected for its growth habit and flower colour and further propagated by cuttings.

Tests & Trials: Trials for 'Sunjodiropi' were conducted in a polyhouse during the spring of 2013 at BioFlora Inc. 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 11.5 cm pots on April 10, 2013. Observations and measurements were taken from 10 plants of each variety on May 16, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
