Origin & Breeding History: 'USCALI518-1' originated from a controlled cross conducted in Hikone, Shiga, Japan on May 17, 2005 between the female parent, proprietary seedling 'C360-01' and the male parent, proprietary seedling 'C376-01'. The new Calibrachoa is the product of a planned breeding program developed by the breeder Ushio Sakazaki, in Shiga, Japan. 'USCALI518-1' was selected as a single plant from the resultant progeny on April 6, 2006 in Gensingen, Germany. Selection was based on semi-double type flowers, growth habit, summer performance and Thielaviopsis resistance. Propagation of 'USCALI518-1' was first conducted by vegetative cuttings on April 6, 2006, in Gensingen, Germany.

Tests & Trials: Trials for 'USCALI518-1' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario. The trial included a 16 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 21, 2009. Each basket contained 4 cuttings with a total of 4 baskets per variety. Observations and measurements were taken from 10 plants of each variety on October 1, 2009. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
