ROSARIUM UETERSEN® – pink climbing rose – KORtersen
Vertical production of ROSARIUM UETERSEN® gives nurseries a reliable, exhibition-grade climber for space-defining features and trained-plant programmes, with own-root stability supporting long-term collection and project use. As a remontant, large-flowered shrub-type climber with dense, glossy foliage, it suits tray-based pharmaROSA® NEONATAL propagation for onward staked training into 3–5-cane forms in 5–7 L containers. Its documented hardiness and disease resistance underpin predictable performance across UK regions, including colder northern sites with strong winter and wind tolerance, while good heat resilience broadens scheduling options. Medium-height, creeping-habit growth enables flexible finishing on pergolas, arches, walls and fences, and the cultivar’s rich, deep-pink, rosette flowers with medium classic fragrance support premium, cut-capable, exhibition-oriented finished lines. In own-root production, a natural progression of strong Year 1 rooting, structure-building Year 2 shoots and full ornamental expression from Year 3 aligns well with nursery planning for vertical garden and collection-led projects.
Usage options
Finished-product ideas
- Premium 5–7 L trained climber – NEONATAL plants staked to 3–5 main canes, focused on vivid deep-pink, rosette clusters and classic fragrance as an exclusive space-defining vertical feature – retail / reseller premium ranges
- Collection pergola series – own-root lines grown on in nursery beds, then containerised for pergolas and arches, using hardiness and disease resistance to support reliable show-garden and thematic rosarium collections – public-realm and institutional suppliers
- Wall and fence accent range – creeping-habit, dense-foliage climbers finished in 5–7 L pots for rapid coverage of walls and fences, emphasising low intervention needs – landscape contractors and project wholesalers
- Exhibition-capable climber line – remontant, large-flowered climbers selected for colour uniformity and cut suitability, trained from NEONATAL stock into uniform caned forms – specialist retail and show-garden partners
- Own-root park and specimen climber – durable, long-lived plants developed in beds then shifted to large feature containers (40–50 L) for park, arch and specimen roles where stability and vertical impact are key – municipal and estate projects
Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Climbing rose in the Climbing rose commercial group; registered as KORtersen, marketed as ROSARIUM UETERSEN® pink climbing rose KORtersen, with ARS exhibition name Rosarium Uetersen. |
| Origin and breeding |
Bred by Reimer Kordes at W. Kordes’ Söhne from ‘Karlsruhe’ × unknown seedling; introduced and registered in Germany in 1977, distributed initially by W. Kordes’ Söhne. |
| Awards and recognition |
Recognised with the Gold Star of the South Pacific at the New Zealand Rose Trials in 1980, alongside further international awards highlighting its ornamental and garden performance. |
| Growth and structural characteristics |
Creeping climber reaching about 200–320 cm high with 80–160 cm spread, dense mid‑green glossy foliage, moderately thorny canes and weak self-cleaning, requiring periodic removal of spent blooms. |
| Flower morphology |
Very double, rosette-shaped medium flowers (around 1.5–2.75 in) with over 40 petals, carried in clusters; remontant flowering with a less abundant second flush under garden and production conditions. |
| Colour data and phenology |
Deep pink flowers (RHS 62B outer, 62C inner) with uniform, radiant colour; buds dark velvety pink, gradually lightening to silvery-pink in strong sun, with an overall even, intense pink at full bloom. |
| Fragrance and aroma |
Pleasant, clearly perceptible classic rose fragrance of medium strength, contributing to both garden and cut-flower value, though the very double form limits pollinator access to nectar and pollen. |
| Hip characteristics |
Rose hips form sparsely due to the double blooms; when present, ovoid, orange-red hips about 12–18 mm in diameter may develop, but ornamental and production impact from hip display is limited. |
| Resistance and winter hardiness |
Good overall disease resistance, rated resistant to powdery mildew, black spot and rust; heat tolerant with irrigation in prolonged drought, and winter hardy to around -32 – -29 °C (RHS H7, USDA 4b, Swedish Zone 5). |
| Horticultural recommendations |
Suited to climbing uses on pergolas, walls, arches, fences and as specimen or park features; low maintenance needs and disease resistance match trained climber production in 5–7 L pots and cut-flower use. |
ROSARIUM UETERSEN® – pink climbing rose – KORtersen offers hardy, disease-resistant, visually striking vertical features on a predictable own-root base, making it a sound option for planning long-term trained climber capacity; please feel free to discuss scheduling and volumes.
