Rosa cannabifolia – pharmaROSA® NEONATAL rooted cutting
Botanical Rosa cannabifolia offers a distinctive landscape shrub profile for nurseries building reliable project ranges, combining proven Alba parentage with low-maintenance, long-lived own-root production. Its bushy, upright habit and moderate, bluish‑ to grey‑green foliage deliver fast visual coverage and uniform hedging or group plantings from 1.5–2 L pots onwards, with scope for onward step-up into 40–50 litre containers for structural roles in thematic rose gardens and public landscapes. Hardy to RHS H7 and USDA 3b, it supports specification in exposed schemes where dependable winter and wind tolerance across Scotland and northern England is required. Disease-resistant foliage and good heat and drought tolerance stabilise quality under nursery and site stress, while the own-root base supports long-term regeneration and predictable, homogeneous stands, following the natural development arc of strong roots in year one, building framework in year two and full ornamental impact by year three, underpinning wholesale-scale projects, cultivar collections, and sustainable stock for professional rose wholesale.
