Korizont Climbing rose KORizont – pharmaROSA® NEONATAL rooted cutting
Professional production of Korizont as pharmaROSA® NEONATAL own-root material offers a reliable climber for trained-finish routes where vertical, space-defining structures are central to your range. As a medium-maintenance, moderately thorny cultivar with 3–5 pre-trained main canes, it supports efficient wall, fence and pergola lines that align well with exclusive, specialty projects. The remontant, large single flowers deliver abundant repeat coral-pink display with a strong, slightly sweet fragrance, fitting thematic rose collections and show gardens used as reference stock. Own-root propagation underpins long-term stability for nursery networks and integrator systems, allowing predictable renewal and reduced replacement over multiple crop cycles. Development typically progresses from rooting focus in year one, structural shoot build-up in year two, to full ornamental performance from year three, matching UK scheduling norms, while its winter performance suits exposed Scottish and northern sites with reliable cold tolerance under nursery management. Tray-rooted cuttings integrate cleanly into container production, from propagation beds through 5–7 L finishing, providing logistical efficiency for wholesale partners who need repeatable capacity and cultivar-authentic stock on own roots for collection and public-realm installations.
