Origin & Breeding History: 'Helisbrabic' was developed by the breeder, D. van Kleinwee, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. It originated from a controlled cross made in 2002 between the female parent designated 'B0541-1' and the male parent designated 'C3185-1'. 'Helisbrabic' was selected from the resultant progeny as a single plant in 2003. In 2004, it was tested as a clone in Enkhuizen, The Netherlands for greenhouse and field performance, earliness, branching, flower colour, flower size and flowering continuity. Also in 2004, it was tested for heat and drought stress resistance in Sarrians, Southern France.
Tests & Trials: Trials for 'Helisbrabic' were conducted in a polyhouse during the spring of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants per variety. Rooted cuttings were transplanted into 15 cm pots on May 13, 2008. Measured characteristics were based on measurements taken from 10 plants or parts of plants on July 2, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
