Puerta del Sol Climbing rose DELglap – pharmaROSA® NEONATAL own-root propagation material
Climbing own-root NEONATAL material of Puerta del Sol offers a vertical solution for nursery beds and container production where collection value and space-defining structure support premium ranges. With a trailing habit to 200–340 cm and dense, glossy dark-green foliage, it is well suited to trained-climber programmes on stakes and frames. Large, cup-shaped, double flowers in a warm, sunlit golden-yellow shade repeat well, with an abundant second flush and a mild, softly sweet fragrance that underpins exhibition hybrid tea and cut-flower positioning. Own-root development supports a predictable arc from root establishment in year one, structural cane build-up in year two, and full ornamental and vertical impact from year three, while its winter performance is reliable for Scottish and northern English schemes with solid frost and wind tolerance for exposed professional sites.

Technical cultivar profile
| Name and registration |
Climbing rose from the Puerta del Sol line, commercial group Climbing rose; registered as DELglap, ARS exhibition name Puerta del Sol, authenticity verified and tracked under item number [1070] 21-006. |
| Origin and breeding |
Bred by Georges Delbard, Roseraies Georges Delbard, France, using complex parentage (‘Queen Elizabeth’ × ‘Provence’; ‘Michèle Meilland’ × ‘Bayadère’), registered and bred in 1971, initial distribution by Roseraies Georges Delbard. |
| Awards and recognition |
No awards, competition results or specific collector recommendations are recorded for this cultivar; selection is based on structural, colour and production characteristics rather than show distinctions. |
| Growth and structural characteristics |
Large-flowered climber with trailing habit, reaching 200–340 cm in height and 80–150 cm spread, forming dense, glossy, dark-green foliage on moderately thorny canes; self-cleaning performance and leaf shed behaviour not provided. |
| Flower morphology |
Large-sized (2.75–3.95 in) cup-shaped, double blooms with 26–39 petals, borne mainly solitary on canes; good repeat-flowering with particularly abundant second flush, suitable for exhibition stems and cut-flower use. |
| Colour data and phenology |
Warm golden-yellow flowers, ARS and RHS codes around 14B outer and 14A inner; buds open bright golden-yellow, then gradually fade to pale, creamy-yellow tones, especially in strong sunlight, with moderate colour retention over time. |
| Fragrance and aroma |
Softly sweet mild fragrance, adding subtle scent without dominating mixed plantings; double flower form limits pollinator access, so the variety is primarily valued for ornamental and structural vertical emphasis rather than ecological function. |
| Hip characteristics |
Rose hips are infrequent due to the double floral structure; where present, they are ovoid, orange-red, around 10–14 mm in diameter, offering occasional late-season interest without significant seeding or self-spread issues. |
| Resistance and winter hardiness |
Moderate overall disease resistance with black spot resistance and moderate susceptibility to powdery mildew and rust; winter hardy to approximately -21 – -18 °C, aligning with RHS H7, Swedish hardiness zone 3 and USDA zone 6b conditions. |
| Horticultural recommendations |
Best used as a pergola, wall or pillar climber and for cut flowers; recommended as a staked, trained climber finished product in 5–7 L or larger containers, with medium maintenance and periodic pest and disease control as required. |
