Origin & Breeding History: The variety 'Osectrawhi' originated from an open pollinated cross, made in Enkhuizen, The Netherlands in the summer of 2004. The female parent was a proprietary line designated as F0241-1 and the male parent was unknown. The resultant seed was sown in a greenhouse in January 2005. The new variety was selected as a single seedling in May 2005 in Enkhuizen based on criteria for flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'Osectrawhi' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of fifteen plants of the candidate and reference varieties. Rooted cuttings were transplanted into 11 cm pots on April 28, 2010. Observations and measurements were taken from ten plants or parts of plants on June 9, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
