Origin & Breeding History: 'KLECA07108' originated from a cross made in Stuttgart, Germany in 2002. The female parent was isolated from half-siblings of the variety coded T 105 (MiniFamous White) and the male parent was unknown. There were 134 genotypes selected in Stuttgart in May 2003, one of which would be designated as 'KLECA07108'. Selection criteria included growth habit, early flowering, flower colour and branching characteristics. The new variety was evaluated in greenhouse trials in Stuttgart and assessed for time of flowering and branching characteristics. Outdoor performance trials were conducted to assess powdery mildew resistance, aphid interactions and rain and wind tolerance.

Tests & Trials: Trials for 'KLECA07108' were conducted in a polyhouse during the spring of 2009 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 30 cm hanging baskets on May 21, 2009. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 8, 2009. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
