Origin & Breeding History: 'USCAL09301' originated from a controlled cross conducted by the breeder, Ushio Sakazaki, between proprietary seedling designated '10CJ04-03' as the female parent and '10CJ70-02' as the male parent. The cross was conducted in Higashiomi, Shiga, Japan, on May 8, 2010. 'USCAL09301' was selected as a single plant from the resultant progeny on May 13, 2011 in Bonsall, California, USA. Its selection was based on flower colour, plant growth habit, and disease and heat tolerance. The first propagation by vegetative cutting of 'USCAL09301' took place on May 14, 2011 in Bonsall, California, USA.

Tests & Trials: The trial for 'USCAL09301' was conducted in a polyhouse during the spring of 2013 at BioFlora Inc. in St. Thomas, Ontario. There were a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm diameter hanging baskets on May 7, 2013. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants or parts of plants on June 13, 2013. All colour determinations were made using the 2007 Royal Horticulture Society (RHS) Colour Chart.
