Origin & Breeding History: 'Lobselila' originated from a controlled cross made in 2001, in Enkhuisen, The Netherlands. The female parent is identified as C0965 and the male parent is identified as B0941. The new variety 'Lobselila' was selected from the resultant progeny as a single plant in April 2002. 'Lobselila' was then tested as a clone one year later for greenhouse and field performance, branching and plant habit, flower colour and size and continuity criteria. Asexual reproduction by cuttings began in April 2002.

Tests & Trials: Tests and trials were conducted in a polyhouse during the summer of 2007 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 23, 2007. Observations and measurements were taken from 10 plants of each variety on June 25, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
