DARWINA – yellow climbing rose – pharmaROSA® NEONATAL
As an own-root climber in the pharmaROSA® NEONATAL range, DARWINA provides professional growers with a stable, long-lived propagation base for vertical, space-defining projects where predictable structure matters. Its vigour supports reliable trained-climber production on pergolas, arches, fences and façades, while the hardy framework (H7, USDA 5b, down to -26–-23 °C) aligns well with UK nursery networks supplying exposed sites. The variety’s disease resistance underpins low-intervention maintenance promises, and the strongly scented, double, golden-yellow blooms add high perceived value to exclusive, vertical-feature ranges. NEONATAL tray-rooted material integrates easily into 5–7 L trained-climber programmes, with own-root longevity and regeneration supporting homogeneous stands, low replacement and dependable restocking over time. In typical development, roots consolidate in year one, shoots build structure in year two and full ornamental impact is reached by year three. This makes DARWINA a strong candidate for collection-based, thematic and show-garden lines, underpinning private-label ranges and specialist reseller assortments with scalable, professional own-root production.

| Growth and structural characteristics |
Climbing growth habit with approximately 200–320 cm height and 170–280 cm spread; moderately dense, glossy, mid-green foliage and moderate thorniness; self-cleaning behaviour not provided, suited to trained, space-defining structures. |
| Flower morphology |
Double-flowered, 26–39 petals, large blooms of about 2.75–3.95 inches, flat, clustered inflorescences; remontant type with an abundant second flush, giving repeated ornamental impact during the season once established. |
| Colour data and phenology |
Intense, warm golden-yellow at opening (ARS yellow, RHS 12B outer, 13C inner) fading through creamy pale yellow to almost cream; colour retention moderate, with a gentle, decorative fading pattern as the flowers age. |
| Fragrance and aroma |
Strong, long-lasting fragrance with a lively, fruity-citrus character; double flower form with 26–39 petals limits pollinator access, so it is not primarily positioned as a pollinator-supporting cultivar for ecological schemes. |
| Hip characteristics |
Occasionally forms rose hips of approximately 10–18 mm diameter; exact hip colour and shape are not provided, and hip production should be considered incidental rather than a primary ornamental feature. |
| Resistance and winter hardiness |
Rated resistant to powdery mildew, black spot and rust, supporting low-intervention management; hardy to about -26 to -23 °C (H7, Swedish zone 4, USDA 5b), suitable for colder or exposed sites within UK nursery networks. |
