Origin & Breeding History: 'USEVO1201' originated from a controlled cross conducted by the breeder, Ushio Sakazaki, between proprietary seedling designated '06E-22' as the female parent and '05E' as the male parent. The cross was conducted in Higashiomi, Shiga, Japan, on July 15, 2007. 'USEVO1201' was selected as a single plant from the resultant progeny on May 23, 2008 in Bonsall, California, USA. Its selection was based on plant growth and habit, a long flowering period, strong garden performance and good flower coverage. The first propagation by vegetative tip cuttings of 'USEVO1201' took place on May 23, 2008 in Bonsall, California, USA.

Tests & Trials: The trial for 'USEVO1201' 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 variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 17, 2013. Observations and measurements were taken from 10 plants or parts of plants on June 12, 2013. All colour determinations were made using the 2007 Royal Horticulture Society (RHS) Colour Chart.
