Origin & Breeding History: 'Fisbimex' originated from a hybridization made in Hillscheid, Germany in 2003. The female parent was the variety 'Marietta Gold' and the male parent was the variety 'Golden Star'. Seed from the cross was taken to Moncara-pacho, Portugal where the first selection of seedlings was made. Cuttings from the selected seedling were taken back to Hillscheid for further examination and for the trial cultivation in the spring through the summer of 2004 and again in 2005. 'Fisbimex' was selected based on criteria for flower type (number of petals) and plant habit.

Tests & Trials: Trials for 'Fisbimex' were conducted during the summer of 2008 in a polyhouse at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants each of the candidate and reference varieties. The plants were grown from rooted cuttings which were transplanted into 11 cm pots on May 13, 2008. Observations and measurements were taken from 10 plants on August 28, 2008. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
