Origin & Breeding History: 'Agbilir' was bred and developed by the breeder, M. Sanders, an employee of Syngenta Seeds B.V., Enkhuizen, The Netherlands. It originated from a controlled pollination made in October 2002 between the female parent designated 'X0052-4' and the male parent designated 'X0101-7'. 'Agbilir' was selected as a single seedling in August 2003 based on its compact plant habit, branching, flower size and flower colour.

Tests & Trials: Trials for 'Agbilir' were conducted in a polyhouse during the spring of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants per variety. Rooted cuttings were transplanted into 15 cm pots on April 13, 2008. Measured characteristics were based on measurements taken from 10 plants or parts of plants on June 11, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
