Seedling selection: ‘Bonica’. Approx 13 years ago, mature hips were harvested from ten 'Bonica' plants. The seeds were extracted and planted into a well structured soil of pH 6. Approximately 200 seedlings were produced and grown on for a further three years to mature plants. One plant displayed outstanding features and produced white flowers. Pollen was collected from this plant and applied to flowers of ‘Bonica’. The seeds produced were planted into fresh soil and yielded 70 seedlings. These seedlings were grown for two years and the candidate variety now known as ‘Rockliz’ was selected having outstanding characteristics.‘Rockliz’ has been budded onto multiflora rootstock in many thousands and has shown to be genetically stable.
