DELstrobla – Les Roses de peintres® bedding floribunda (own-root propagation)
Floribunda production of DELstrobla as pharmaROSA® NEONATAL own-root material provides a compact, bushy base for uniform 2–3 L container lines and standard finished products aimed at retail and reseller channels. The cultivar’s remontant, clustered flowering supports reliable garden performance positioning, with fully double, cup-shaped blooms delivering distinctive red-white colour striping that retains strong ornamental impact even as tones gently evolve. Medium fragrance strength with a fresh, fruity, raspberry character adds perceived value for cut-flower and bedding-focused assortments, while moderate disease resistance supports manageable, medium-maintenance programmes in nursery beds and urban green space supply. Own-root material underpins stable, renewable growth and predictable stand structure, valuable for UK nursery networks managing varied regional exposure and nationwide, island-route logistics. Over a natural development arc from first-year roots through second-year structural build to full third-year ornamental expression, DELstrobla offers a steady, credible base for thematic rose ranges and collection-style projects.

| Growth and structural characteristics |
Bushy, upright habit, 75–105 cm high with 45–65 cm spread, dense dark green glossy foliage, moderately thorny shoots, weak self-cleaning so deadheading is advisable to maintain flower quality and display. |
| Flower morphology |
Fully double, cup-shaped flowers with 26–39 petals, large size in the 2.75–3.95 inch range, carried mainly in clusters, with remontant behaviour and an abundant second flush under suitable cultural conditions. |

| Fragrance and aroma |
Medium-strength scent, clearly noticeable in flower beds and container displays, with a fresh, fruity, raspberry character that supports fragrance-led ranges; not primarily intended for cosmetic extraction uses. |
| Hip characteristics |
Rose hip set is generally scant due to the fully double flower form; where produced, hips are small, 8–12 mm, ovoid and orange-red, with minimal visual impact compared with the striped floral display. |
| Resistance and winter hardiness |
Moderate resistance to powdery mildew, black spot and rust under professional care, with hardiness down to approximately -21 to -18 °C, rated RHS H7, suitable for USDA zone 6b and Swedish zone 3 climates. |
