In August 2015, seed was sown from a directed cross between two breeding lines. In December these seedlings flowered for the first timeand the variety was selected on the basis of flower colour and fragrance. Cuttings were taken (Gen 1) to test propagation potential and further test horticultural traits. Four more generations of cuttings were taken between April 2016 and March 2017 and the variety has been uniform and stable for the traits it was selected. Breeder: John C. Gray, Sylvia E. Gray, Highfields, QLD.

`GRAosr` is a seedling selection which resulted from the controlled cross-pollination of an unnamed Rosa hybrid female breeding line and an unnamed Rosa hybrid male breeding line. ...fter many years of trialing, the female parent was confirmed to possess a combination of desirable traits such as very strong fragrance and having flower color white, borne on a bushy plant growing to 1.2 m tall and wide. The male parent was selected for use in breeding after trialing confirmed the presence of a modern flower color. During the spring of 2014, the female parent was emasculated and was manually pollinated with pollen from the male parent.
