Florence Delattre Générosa® MASflodel – pharmaROSA® NEONATAL rooted cutting
Générosa® shrub roses such as Florence Delattre offer reliable own‑root propagation material for professional growers seeking a distinctive, purple-toned bed and cut-flower shrub with remontant flowering and strong, rose‑oil fragrance. Supplied as tray‑grown, 3–6‑month‑old rooted cuttings, this compact, bush‑trained form integrates smoothly into container-based nursery systems, particularly where a 2–3 L standard container route is preferred for a premium yet accessible retail shrub. Its dense, dark green, glossy foliage, resilient H7 hardiness to around −26 °C and documented resistance to powdery mildew, black spot and rust support low‑intervention production and dependable garden performance. In the UK context, this underpins supply for thematic rose gardens and collection projects, including public‑realm schemes in cooler, wind‑exposed regions where winter durability matters. Own‑root plants develop progressively—roots in year one, structural framework in year two, and full ornamental value by year three—supporting long‑term, homogeneous stands with low replacement demand. With moderately ornamental red hips and moderate pollinator interest, the cultivar can support both decorative and ecological narratives in wider assortments designed for nursery and wholesale channels, while the stable own‑root base simplifies planning of volume and scheduling for collection‑driven ranges.

| Growth and structural characteristics |
Bushy shrub reaching approximately 120–160 cm in height and 90–130 cm in spread, with dense, dark green, glossy foliage and moderate prickliness; spent flowers are weakly self‑cleaning and generally require manual removal. |
| Flower morphology |
Semi‑double, cupped blooms with 13–25 petals, medium sized at roughly 1.5–2.75 inches, most often in clustered inflorescences, delivering remontant flowering with a generous second flush during suitable conditions. |
| Colour data and phenology |
Pale mauve‑lilac base with greyish‑lilac hue and faint creamy‑yellow centre; colour is richer in cool conditions and fades in strong heat to dusky rose‑purple, then towards an almost greyish lavender tone as blooms age. |
| Fragrance and aroma |
Strong, pronounced fragrance with a spicy, rose‑oil character considered a key ornamental and sensory feature; semi‑double flowers with 13–25 petals provide moderate pollinator interest due to partial stamen accessibility. |
| Hip characteristics |
Forms moderately abundant, spherical red hips, approximately 8–12 mm in diameter, providing additional ornamental interest and seasonal structure where spent blooms are not fully removed after flowering. |
| Resistance and winter hardiness |
Rated resistant to powdery mildew, black spot and rust; hardy to approximately −26 to −23 °C (RHS H7, Swedish zone 4, USDA 5b); requires regular watering as heat and drought tolerance are low and prolonged drought is not tolerated. |
| Horticultural recommendations |
Suited to flower beds, specimen use and garden cutting; compact bush‑trained form recommended for standard 2–3 L container production, with low general maintenance needs and good disease resistance, albeit weak self‑cleaning of spent blooms. |
