Mamy Blue™ Grands Parfums DELblue – pharmaROSA® NEONATAL rooted cutting
Fragrance and colour are at the centre of Mamy Blue™ as a premium hybrid tea for professional production, where its very strong, violet‑honey perfume and distinctive purple‑lilac tonality support an exclusive positioning in exhibition and retail cut‑flower ranges. As a pharmaROSA® NEONATAL own‑root cutting, it offers a stable propagation base for nursery beds and container grow‑on, with predictable structure from its upright, bushy habit and 3–5‑cane bush‑trained release form, making it easy to channel into 5–7 L containers or larger show pieces. You gain a reliable foundation for thematic collections and high‑value selections in dedicated rose gardens, supported by UK distribution designed for exposed northern sites where winter and wind resilience are important, enabling coordinated supply for nurseries, wholesalers and integrator networks. The long‑term own‑root framework underpins repeated cropping for cut‑flower and specimen use, from root establishment in year one through structural build‑up in year two to full ornamental and fragrance expression from year three onwards, supporting predictable scheduling and homogeneous blocks even under intensive production. While disease management and deadheading need to be planned into your programme due to higher maintenance requirements and weak self‑cleaning, the strong flower form, remontant behaviour and stable colour progression provide clear value in premium hybrid tea assortments and private‑label concepts aligned with fragrance‑led, collection‑grade offerings.
