Delstror Les Roses de peintres® DELstror – pharmaROSA® NEONATAL rooted cutting
For professional growers seeking differentiated own-root floribunda stock, Delstror offers a compact, bushy framework ideal for bedding and group plantings, with remontant, clustered flowering that supports reliable, season-long colour in retail-standard 2–3 L containers. The semi-double, cup-shaped blooms display a distinctive salmon-pink base richly variegated with white and pale pink streaks, positioning this cultivar as a characterful choice for thematic rose gardens and curated collections. On own roots it develops a renewable framework with stable ornamental value over time, supporting low replacement rates and predictable display in nursery and public-realm supply chains. Grow-on programmes can be scheduled in a clear development arc—roots in year one, structural shoots in year two, and full ornamental value by year three—well aligned with UK nursery planning horizons. H7 hardiness and USDA 6b performance mean it copes reliably with colder UK regions, offering confident landscape provisioning even where winters are brisk and windy.

Floribunda bedding rose, registered as DELstror, marketed as Delstror Les Roses de peintres DELstror, with ARS exhibition name Grimaldi referencing Monaco’s ruling house anniversary. |
| Origin and breeding |
Bred in France in 1990 by Georges and Guy Delbard, introduced by Pépinières et Roseraies Georges Delbard in 2001 in France and 2002 in the United Kingdom, registered in 1998. |
| Awards and recognition |
Recognised at Monza rose trials with People’s Choice in 1998 and Silver Medals in 1998 and 1999, underlining strong visual and public-appeal performance in competitive evaluation. |
| Growth and structural characteristics |
Bushy, medium-height shrub reaching 90–115 cm in height and 95–125 cm spread, medium foliage density with dark green leaves and moderate prickliness, offering compact yet substantial structural presence. |
| Flower morphology |
Semi-double, cup-shaped blooms of medium size, typically 13–25 petals, borne in clusters, with remontant flowering that includes a plentiful second flush, giving extended ornamental coverage through the season. |
| Colour data and phenology |
Salmon-pink base with white and pale pink streaks; buds vibrant salmon pink with creamy-white shading, flowers lighten in sun, showing cream-white mottling and softening tones as they age, with moderate colour retention. |
| Fragrance and aroma |
Mild but distinct fresh, fruity-rosy fragrance, providing a restrained scent suitable for close-planting contexts; semi-double form offers partial pollinator friendliness compared with more densely filled roses. |
| Hip characteristics |
Hip set is irregular; where formed, hips are small at 0–8 mm diameter, with occurrence and decorative value limited, so hips are generally not a primary ornamental or production feature. |
| Resistance and winter hardiness |
Hardy to approximately −21 to −18 °C (RHS H7, Swedish Zone 3, USDA 6b), with moderate heat and drought tolerance needing irrigation in prolonged dry periods, and moderate to sensitive responses to common foliar diseases. |
| Horticultural recommendations |
Suitable for beds, groups, containers, hedges, parks and some cutting; requires regular inspections and frequent plant protection due to weaker disease resistance; supplied as bush-trained, compact plants for standard containers. |
