Origin & Breeding History: 'RIKAV44101 was bred and developed by the breeder, Rika Matsumoto, in Higashiomi, Shiga, Japan. It originated from a controlled cross conducted on May 18, 2015, between a seedling designated '13V349-02', as the female parent, and a seedling designated '13V308-02', as the male parent. From the resulting progeny, 'RIKAV44101' was selected on May 26, 2016, in Bonsall, California, USA, for its plant growth habit, flower size, and resistance to powdery mildew. Asexual reproduction of 'RIKAV44101' was first conducted by vegetative cutting on May 30, 2016, in Bonsall, California, USA.

Tests & Trials: The comparative trial for 'RIKAV44101' was conducted in a polyhouse during the spring of 2019, in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm diameter pots on April 15, 2019. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 4, 2019. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
