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.

Michael Marriott, the technical manager of David Austin, states that 'Olivia Rose Austin' took 9-10 years to develop from the original cross. It is named after the daughter (b. 1995) of David Austin, Jr.
