Origin & Breeding History: 'Goalia Oran' was developed as part of a planned pedigree breeding program by the breeder, Pim Kaagman, of Goldsmith Seeds Europe B.V. in Andijk, The Netherlands. It originated from a cross made in September 1999 between 'DT-32-2' as the female parent and 'DU-43-1' as the male parent. In May 2002, 'Goalia Oran' was selected based on its flower colour, flower form and plant growth habit.

Tests & Trials: Trials for 'Goalia Oran' were conducted in a polyhouse during the summer of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 10, 2007. Observations and measurements were taken from 10 plants of each variety on July 27 and August 8, 2007. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
