Origin & Breeding History: 'Kakegawa S68' originated from a hybridization conducted in November of 1999 in Kakegawa, Japan. The female parent was an unnamed breeding line with red flowers and semi-creeping plant growth habit designated '9B-58C' and the male parent was another unnamed breeding line with rose coloured flowers and a mounding plant growth habit designated '7BC-42A-1'. In February of 2000, F1 seed was sown and five plant selections were made based on their red flowers and erect plant habit. These selections were intercrossed to produce F2 seed. In August of 2000, the F2 seed was sown. From the resulting seedlings, 120 were evaluated. One plant was selected based on its rose coloured veins and semi-creeping plant growth habit and subsequently named 'Kakegawa S68'.

Tests & Trials: The test and trial for 'Kakegawa S68' was conducted in a polyhouse at Variety Rights Management in Oxford Station, Ontario during the summer of 2005. The trial included 15 plants of each variety grown in 10 cm pots. The plants were spaced 13 cm apart. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten measurements.
