Origin & Breeding History: 'Agbapur' was bred and developed as part of a planned breeding program by the breeder Monica M.A. Sanders at Syngenta Seeds B.V., Enkhuizen, The Netherlands. The new variety originated from a controlled pollination of a female Ageratum houstonianum plant identified as Y0017-3 with pollen from a male Ageratum houstonianum plant identified as Y0039-3. The cross was made in October 2003 in Enkhuisen, The Netherlands. The resultant seed was sown in January 2004. 'Agbapur' was selected as a single seedling in August 2004 in Enkhuizen based on growth habit, branching, flower size and flower colour. Asexual reproduction by cuttings of 'Agbapur' was first conducted in Enkhuizen in September 2004.

Tests & Trials: Trials for 'Agbapur' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on May 12, 2010. Observations and measurements were taken from 10 plants of each variety on June 16, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
