Origin & Breeding History: 'Ausjive' originated at Bowling Green Lane, Albrighton, England, in 2000. This variety was produced by normal sexual hybridization of two unnamed parent varieties. It was selected by the breeder as it forms a good, branching shrub that is healthy and repeat flowers extremely well.

Tests & Trials: Trials for 'Ausjive' were conducted in an outdoor trial during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. Trials included 10 plants of the candidate variety and 9 plants of the reference variety. Plants were grown from bare-rooted plants, transplanted into 13.2 litre containers in May, 2012. Observations and measurements were taken from 10 plant parts of each variety on August 15, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
