Sénégal Climbing rose Mallerin – pharmaROSA® NEONATAL propagation material
Climbing production of exclusive dark-red cultivars such as Sénégal offers professional growers a reliable own-root base for vertical, space-defining ranges where colour depth, strong fragrance, and dense foliage support high-impact pergola, wall, and fence lines. This cultivar’s remontant, double, cut-flower-capable blooms and low-intervention maintenance profile suit trained climber programmes in 5–7 L containers, feeding into retail and reseller channels focused on specialty show and collection planting. Own-root tray material gives predictable, renewable growth that fits UK nursery schedules, performing steadily even in exposed northern sites with reliable winter and wind tolerance, while enabling planned throughput from propagation beds to finished, staked product. Year one prioritises root establishment, year two builds structural canes, and by year three the full ornamental value of this cultivar can be presented consistently across batches.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Current trade name Sénégal Climbing rose Mallerin, American Rose Society exhibition name Sénégal; large-flowered climbing rose within the climbing rose commercial group; not a registered variety. |
| Origin and breeding |
Bred in France by Charles Mallerin around 1944, with parentage not provided; introduced by Meilland et Cie, France; breeding and introduction correspond to the same period, reflecting classic mid-twentieth-century selection. |
| Awards and recognition |
Not provided; no competition, collector, or lifetime awards recorded in the available dataset, so positioning is based primarily on technical performance, garden value, and historic breeder provenance rather than on formal distinctions. |
| Growth and structural characteristics |
Strong climbing habit with dense, dark green, glossy foliage; height typically 300–450 cm with 160–260 cm spread; densely thorned canes; some spent blooms remain and may need manual removal to maintain presentation quality. |
| Flower morphology |
Large, double, cup-shaped blooms with approximately 26–39 petals, borne mainly as solitary flowers; remontant with abundant second flush, providing extended ornamental value and supporting both garden use and potential cut-flower applications. |
| Colour data and phenology |
Deep velvety dark red with blackish base tones; ARS code DR, RHS 187A outer and 187B inner; colour holds well, lightening slightly to carmine red with burgundy edge in heat, while buds appear dark burgundy to almost black before opening. |
| Fragrance and aroma |
Strong, distinctive scent with classic rose character and spicy notes, giving high perceived value in both garden and cut uses; many-petalled flowers reduce pollinator access, so the variety functions primarily as an ornamental and sensory feature. |
| Hip characteristics |
Rose-hip formation is typically sparse; where present, hips are red, egg-shaped, around 12–18 mm in diameter, appearing occasionally and adding modest seasonal interest without strongly influencing maintenance or propagation practices. |
| Resistance and winter hardiness |
Rated resistant to powdery mildew, black spot, and rust; hardiness approximately −18 to −15 °C, RHS H6, Swedish Zone 2, USDA 7a; tolerates heat well and moderate drought with supplementary irrigation during prolonged dry weather. |
| Horticultural recommendations |
Recommended for pergolas, fences, walls, cut-flower use, and specimen planting; low maintenance needs with generally good disease resistance; best marketed as a trained climber finished product, typically in 5–7 L containers with 3–5 main canes. |
