Rhea Hybrid tea rose pharmaROSA® NEONATAL – professional own-root starting material
With Rhea as a pharmaROSA® NEONATAL own-root cutting, You are working from a stable propagation base designed for premium container production and exclusive retail positioning. Its compact, barely thorny, bush-trained habit with 3–5 framework canes gives predictable structure in 5–7 L lines and simplifies handling in nursery systems. The very full, solitary, exhibition-grade flowers combine rich wine-red colour retention with strong fragrance, supporting high-value “cut flower / collector” ranges and thematic rose garden concepts. Reliable disease resistance and low maintenance needs translate directly into homogeneous stands, low replacement, and even bench quality across production cycles. Own-root technology offers long lifespan, regeneration after hard pruning, and stable ornamental value under repeated cropping pressure. In typical UK conditions it shows good tolerance of heat and shorter dry spells, supporting supply chains where summers can be hotter and drier than average in the south-east. Rhea’s low hip set, premium flower form, and bush-trained framework fit neatly into nursery propagation beds and container grow-on programmes targeting exclusive finished goods. From Year 1 roots through Year 2 top growth to full Year 3 ornamental value, this cultivar supports planned capacity and long-term collection planting. Within a wholesale-scale, own-root platform of over 1600 cultivars, Rhea strengthens Your portfolio with a distinctive red hybrid tea suited to both cut flower and garden specimen use, while the uniform tray-rooted material is easy to schedule, store, and integrate into existing nursery workflows.
