Rosa pimpinellifolia Mary Queen of Scots – pharmaROSA® NEONATAL
As a historical landscape shrub rose on own roots, Rosa pimpinellifolia Mary Queen of Scots offers growers a robust, uniform propagation base for border, hedging and project-led ranges, with dense, bushy structure and reliable once-season flowering. Its moderate heat tolerance and very high winter hardiness support consistent performance in exposed UK sites, for example where strong winds and low winter temperatures must be accommodated. Strong disease resistance and low maintenance needs reduce plant protection inputs, while self-cleaning flowers and ornamental hips sustain visual value well beyond the flowering window. The semi-double, pollinator-friendly blooms with visible stamens add ecological diversity to project portfolios, and own-root longevity supports stable, repeatable mass-planting schemes in nursery networks. With tray-rooted cuttings designed for 1.5–2 L production and eventual use in large-scale project mass planting, this cultivar delivers a predictable, premium component for thematic rose collections and wholesale supply, following the natural development arc from root establishment in year one, structural build in year two and full ornamental expression from year three.
