This pharmaROSA® NEONATAL own-root cutting arrives tray-rooted at a uniform stage, supporting predictable propagation and efficient scheduling into the recommended 5–7 L premium container route, where its upright, 135–225 cm habit and dense, dark green foliage quickly build presence.

As an exclusive finished product proposition focused on flower form and quality, it fits retailers and resellers seeking character-rich English Roses; you can anticipate the typical own-root development arc from root establishment in year one, through framework shoot build-up in year two, to full ornamental performance from year three for stable, long-term value.

| Growth and structural characteristics |
Upright shrub, around 135–225 cm high with 90–150 cm spread; dense, dark green, slightly glossy foliage; densely thorned shoots; poor self-cleaning so deadheading of spent blooms is advisable. |

| Fragrance and aroma |
Very strong, garden-filling scent with full, old-rose character; high ornamental fragrance value but very double form reduces stamen access, so pollinator interest is relatively limited in typical plantings. |
