Madame Grégoire Staechelin – pharmaROSA® NEONATAL own‑root rambler climbing rose
As a tray-grown pharmaROSA® NEONATAL own‑root rambler, Madame Grégoire Staechelin offers a highly adaptable vertical solution for professional propagation beds and containerised grow‑on, supporting exclusive, space‑defining finished climber ranges. Its vigorous climbing habit and dense, glossy foliage allow You to structure pergola, wall and arch lines reliably, while own‑root stability underpins long‑term collection and project plantings with low replacement and predictable capacity. The medium maintenance profile aligns well with nursery networks and reseller routes that require balanced workload and consistent quality for trained climber finished products in 5–7 L. The once‑blooming, semi‑double, clear pink flowering display is complemented by pear‑shaped, orange‑red hips in autumn, creating a coherent, specialty vertical garden feature for thematic and show gardens in the UK. In established stands it tolerates heat and moderate drought well, supporting production for warmer or more exposed schemes with dependable performance even in challenging, sun‑exposed situations. With medium disease resistance and strong, award‑backed heritage, it suits integrator systems and public‑realm suppliers seeking reliable, own‑root material that develops roots in year one, structural shoots in year two and full ornamental value from year three onwards.
