Origin & Breeding History: The new cultivar was developed from a half-sib cross, KA-99-4/6, between two unnamed parental lines of Lobelia during 1998 in Mariahout-Laarbeek, The Netherlands. The F1 seedlings were grown out in 1999 and evaluated over several years for flower colour, flower size and trailing habit. In 2003, the new variety was selected based on ease of propagation and flower colour.
Tests & Trials: Trials were conducted during the summer of 2006 in Oxford Station, Ontario. Trials consisted of 15 plants of each variety individually grown in 10cm pots in a polyhouse. Plants were spaced 30 cm apart. Observations and measurements were taken on 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
