PRINCESSE DE MONACO ® – white‑pink hybrid tea rose – Meilland
Exclusive own‑root pharmaROSA® NEONATAL material of Princesse de Monaco offers professional growers a stable basis for premium hybrid tea cut flower and container production, with upright habit and dense, dark‑green foliage supporting clean, exhibition‑grade bloom presentation. Strongly remontant flowering and colour stability enable reliable programme planning for retail and reseller channels, while the high‑centred buds and XL flowers match UK expectations for hybrid tea show and specimen use. On own roots, regenerative growth supports long‑term bed and premium container cropping, complementing a bush‑trained release form with 3–5 strong canes for a fast transition into 5–7 L premium containers and, where required, 40–50 L feature pots. Good heat and drought tolerance provides secure performance for nursery networks serving warmer and more exposed UK sites, supporting projects where reliable flowering under summer pressure is essential. Over time, year‑1 root establishment, year‑2 structural build and year‑3 full ornamental value give predictable field and container performance for thematic rose collections and public‑realm‑oriented stock planning, enhancing credibility and scheduling confidence across integrated supply systems.
