Origin & Breeding History: 'Hoobenihime' originated as a whole plant mutation of the petunia breeding line 'Usubenihime' discovered in May 2007 in Kanagawa, Japan. The new variety was selected based on flower colour and flower size. From November 2007 through 2008, the selected plant was vegetatively propagated from cuttings and trialed repeatedly to assess uniformity. In April 2009, the selection was confirmed to reproduce true to type in successive generations of asexual propagation and was subsequently named 'Hoobenihime'.

Tests & Trials: Trials for 'Hoobenihime' were conducted in a polyhouse during the spring of 2012 at BioFlora in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 25, 2012. Observations and measurements were taken from 10 plants of each variety on May 25, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
