Institut Lumière Romantic rose MASinlum – pharmaROSA® NEONATAL rooted cutting
With its Romantic flower form and salmon-pink colour gradient, Institut Lumière offers premium visual impact for dedicated rose ranges while remaining manageable to produce at scale in own-root form. This bushy shrub habit, dense dark-green foliage and medium height-spread profile suit structured nursery layouts, whether for 5–7 L premium containers or subsequent transfer to 40–50 litre and larger landscape units. The very double, cupped blooms with remontant repeat and medium, softly sweet fragrance support exclusive finished-product positioning focused on flower quality and nostalgic appeal. Own-root NEONATAL material provides a renewable base for long-term stock beds and collection plantings, giving predictable stands, low replacement rates and reliable capacity under UK nursery conditions, particularly where winter and wind exposure are considerations in Scotland and northern England. Over a natural development arc, roots establish in year one, structural shoots stabilise in year two and full ornamental value expresses from year three, aligning well with professional scheduling. Moderate hardiness to approximately -21 °C and balanced resistance enable consistent outputs when combined with routine care, making this cultivar a practical, premium element within thematic Romantic rose assortments for trade and project supply.

| Growth and structural characteristics |
Bushy shrub with 85–115 cm height and 70–90 cm spread, moderately thorny canes and dense, matte, dark-green foliage; supplied bush-trained with 3–5 strong framework canes for premium container structures. |
| Flower morphology |
Very double, cupped blooms with 40+ petals, large flower size around 2.75–3.95 inches, borne singly or in clusters of 1–5 per stem; remontant habit with an abundant second flush under suitable culture. |

| Fragrance and aroma |
Medium-strength, softly sweet fragrance clearly noticeable at close range; primarily an ornamental variety, as the very full flower form conceals stamens and offers limited pollinator attraction under garden conditions. |
| Hip characteristics |
Very double flowers reduce hip formation; only occasional ellipsoidal red hips of about 8–12 mm diameter appear, with minimal impact on ornamental value or energy allocation in standard professional production. |
| Resistance and winter hardiness |
Rated to approximately -21 to -18 °C, RHS H7, Swedish zone 3, USDA 6b; moderate tolerance to heat and drought with irrigation, and moderate resistance to powdery mildew, black spot and rust under managed care. |
| Horticultural recommendations |
Suitable for flower beds, parks, specimen use and cut flowers; moderate maintenance with occasional pest and disease control; best directed to premium container production, especially 5–7 L, from own-root NEONATAL material. |
Institut Lumière Romantic rose MASinlum combines large nostalgic blooms, bushy structure and moderate hardiness with the predictability and regeneration of own-root production, making it a considered choice for aligning long-term capacity and project scheduling.
