Origin & Breeding History: 'USCALI99' originated from controlled cross conducted in Hikone, Shiga, Japan on April 5, 2000. A purple flowered seedling designated as C2903 was the female parent and a blue flowered seedling designated as K-1 was the male parent. The new variety was selected as a single plant from the resultant progeny on June 24, 2001, in Gensingen, Germany. It was selected based on a semi-upright plant habit, tolerance to heat, flower size, and Thielaviopsis resistance. The new variety was first propagated by vegetative cuttings in Gensingen, Germany on June 24, 2001.

Tests & Trials: The tests and trials for 'USCALI99' were conducted in a polyhouse during the summer of 2006 in St. Thomas, Ontario. The trial included a total of 20 plants of each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 25 cm baskets on April 20, 2006. Each basket contained 3 cuttings with a total of 7 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 12, 2006. All colour measurements were made using the RHS Colour Chart 2001.
