'Kakegawa S91' has shorter leaves than 'Dancalipet'. The flowers of 'Kakegawa S91' are funnelform and more than three coloured while those of 'Dancalipet' are salverform and only one coloured. The apex of the corolla lobe is retuse (shallow emarginate) for 'Kakegawa S91' while it is rounded to cuspidate for 'Dancalipet'. The upper side of the corolla of 'Kakegawa S91' is orange with randomly distributed light yellow orange areas and purple red around the margins and along the corolla lobe mid-veins whereas for 'Dancalipet', it is bright purple with purple red tones which are darker at the area of transition to the corolla tube. 'Kakegawa S91' has yellow secondary colour at the area of transition to the corolla tube while 'Dancalipet' has no secondary colour.

Origin & Breeding History: 'Kakegawa S91' was developed by the breeder, Akinobu Ui, an employee of Sakata Seed Corporation, Japan. It originated from a hybridization between a proprietary hybrid Calibrachoa line and a proprietary hybrid Petunia line made in May 2003 in Kakegawa, Japan. In December 2003, 6 intergeneric hybrid plantlets were transplanted to soil-less media for greenhouse culture and acclimatization. In March 2004, these plantlets were vegetatively propagated to produce rooted cuttings and in April 2004, they were transplanted to an open field and evaluated until July 2004 for flower colour and plant growth habit. 'Kakegawa S91' was selected in August 2004 based on its bright "terracotta" flowers (apricot with pinkish-red veins) and mounding plant growth habit. Ten (10) cuttings of 'Kakegawa S91' were further evaluated in open field trials from September to November 2004. These trials were used to confirm that the distinctive characteristics of 'Kakegawa S91' are fixed and stable.
Tests & Trials: Trials for 'Kakegawa S91' were conducted in a poly-house during the summer of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen (15) plants per variety. All plants were grown from rooted cuttings and transplanted into 11.5 cm pots on July 10, 2007. Observations and measurements were taken from ten (10) plants or parts of plants on August 30, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
