A single plant from the progeny was selected by the breeder on November 6, 2007 in Alva, Florida. The new variety was selected based on criteria for flower colour, flower type, flower size, early flowering, response time and plant habit.

Tests & Trials: Trials for 'Syaub Oran' were conducted in an outdoor irrigated trial during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 20 cm pots on June 23, 2011. Observations and measurements were taken from 10 plants of the candidate variety on September 27, 2011 and the reference variety on September 30, 2011.
