In 2006, at the nursery of David Austin Roses Limited, Bowling Green Lane, Albrighton, Wolverhampton, UK, an unnamed seedling was selected to be the mother and an unnamed seedling was selected to be the father. The resulting seed was sown in January 2007, from which several seedlings grew. The best of these seedlings was then selected and from this plant, in July 2007, 8 buds were taken and grafted (using the 'T-budding' method) onto Rosa Laxa root-stock outdoors. The following year, in 2008, the variety was considered good enough to be increased by grafting to 30 plants. Next year, in 2009, the increase was up to 200, and two years after that, in 2011, it was increased to 1,500. In 2013 the variety was increased by further budding to 5,000, sufficient budding for a commercial introduction in the UK in May 2014

 

This invention relates to a new and distinct variety of shrub rose plant named `AUSmixture`, which was originated from the cross-pollination of the two `unnamed` and unpatented seedlings of Rosa hybrida...The following description is of 5-year-old trial rose plants of the new variety grown in a garden environment in Albrighton, Britain in the month of June.
