Chantal Mérieux™ Générosa® – pharmaROSA® NEONATAL rooted cutting
Premium own-root pharmaROSA® NEONATAL material of Chantal Mérieux™ Générosa® offers a bushy, upright, medium-sized shrub framework that suits efficient, repeatable nursery production for container routes and premium border or specimen roses. With very double, mid-pink flowers in a nostalgic rosette form and a very strong, classic rose-fruity fragrance, it targets exclusive, flower-quality-led finished lines where visual impact and scent justify higher retail positioning. Good disease resistance and low maintenance needs reduce intervention during the 3–6 month grow-on phase and beyond, supporting homogeneous batches and predictable scheduling. Its H7 hardiness and USDA Zone 6b tolerance help support production for cooler UK regions, combining winter reliability with manageable heat tolerance and watering needs, providing confidence for nursery networks and public-realm-focused suppliers across Scotland and Northern England, where winter and wind resilience are important. As own-root propagation base material, it can reliably build renewable stock for premium 5–7 L bush-trained container production with 3–5 strong framework canes, fitting nursery and wholesale partners seeking stable long-term cultivar lines.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Registered as MASchame, traded as Chantal Mérieux™ Générosa® MASchame, a Romantica shrub nostalgia rose; ARS exhibition name Chantal Mérieux supports consistent professional identification. |

| Awards and recognition |
not provided |
| Growth and structural characteristics |
Bushy, upright shrub reaching around 75–110 cm in height and 55–80 cm spread, with dense, glossy medium-green foliage and moderate prickliness, offering a compact yet substantial framework. |
| Flower morphology |
Large, very double rosette blooms with 40+ petals, typically in clusters of 1–3 per stem, repeat-flowering with a plentiful second flush; weakly self-cleaning, so spent blooms benefit from manual removal. |
| Colour data and phenology |
Mid-pink flowers with silvery sheen; RHS 57C outer and 65C inner, opening deep pink then shell-pink, fading to pastel with almost whitish-silver petal edges, offering layered colour dynamics as blooms age. |
| Fragrance and aroma |
Very strong, classic rose-fruity fragrance, noticeable from a distance; primarily an ornamental variety with highly double flowers that limit access to stamens, so not optimised for pollinator support. |
| Hip characteristics |
Hip set is generally limited due to the very double flowers; where present, small globular orange-red hips of about 9–12 mm diameter may develop, adding occasional late-season interest. |
| Resistance and winter hardiness |
Shows resistance to powdery mildew, black spot and rust; hardy to approximately -21 to -18 °C (H7, Swedish Zone 3, USDA 6b) and tolerates heat well with supplemental irrigation in prolonged dry spells. |
| Horticultural recommendations |
Recommended for borders, specimen use and cut flowers, with low maintenance needs; best finished as bush-trained plants with 3–5 canes in 5–7 L premium containers, leveraging flower quality and form. |
Chantal Mérieux™ Générosa® as pharmaROSA® NEONATAL own-root material combines strong fragrance, reliable shrub structure and good disease resistance with predictable, regenerative stands, making it a sound candidate for discussing capacity, timelines and tailored supply.
