Origin & Breeding History: The variety 'USCAL68604' originated from a controlled cross conducted in Higashiomi, Shiga, Japan on May 8, 2007. The female parent was a proprietary seedling with pink flowers with a black eye, designated C582-01B, and the male parent was a proprietary seedling with purple coloured flowers with a large black eye, designated CJ07-17. The new calibrachoa was selected as a single plant from the resultant progeny on May 21, 2008 in Bonsall, California, USA. The variety was selected based on criteria for novel flower and eye colour and flower form. 'USCAL68604' was first propagated by vegetative cuttings on July 23, 2008 in Bonsall, California, USA.

Tests & Trials: Trials for 'USCAL68604' were conducted in a polyhouse during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 11, 2011 and cut back on July 5, 2011. Each basket contained 3 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on August 2, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
