Bajazzo® Klettermaxe® KORteheba – pharmaROSA® NEONATAL own-root climbing rose propagation material
Vertical production concepts benefit from Bajazzo® Klettermaxe® KORteheba as an own-root pharmaROSA® NEONATAL starting point, delivering climbing structure with dense dark-green foliage and large single, cluster-flowered heads that are highly attractive to pollinators. The vibrant, deep-to-pastel pink colour shift provides strong impact for exclusive, space-defining finished climbers, supporting retail and reseller positioning as a speciality, colour-focused pillar or pergola feature. Own-root material underpins long-term longevity and regenerative capacity, reducing replacement risk in nursery beds and vertical feature stock for UK project work, while reliably supporting thematic and collection plantings. Its height range of 200–320 cm enables trained, staked production as a premium feature line in 5–7 L containers, with scope to step up to 40–50 litre specimens for mature, ready-structured vertical elements; the variety tolerates UK winter and wind conditions well, allowing planning for exposed show-garden structures and public-realm style installations in Scotland and northern England within nursery and wholesale supply chains over a realistic development arc from root establishment in year one, framework building in year two, and full ornamental value from year three.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Large-flowered climber from the Klettermaxe® collection; registered as KORteheba and marketed as Bajazzo® Klettermaxe® KORteheba, including Bajazzo as the approved exhibition name. |
| Origin and breeding |
Bred by Tim-Hermann Kordes at W. Kordes’ Söhne, Germany, in 2001; registered in 2010 and introduced commercially in 2011, with initial distribution handled by W. Kordes’ Söhne. |
| Awards and recognition |
Holds the ADR award (Germany, 2010) plus multiple international trial distinctions including Baden–Baden Silver Medal, RNRS Trial Ground Certificate, and prizes at The Hague and Vienna rose competitions. |
| Growth and structural characteristics |
Climbing habit with dense, dark green glossy foliage, densely thorned shoots, height 200–320 cm and spread 70–120 cm, forming a substantial vertical framework for pergolas, pillars and walls. |
| Flower morphology |
Large, single, cup-shaped flowers with 5–12 petals, produced in clusters; remontant with a strong second flush, medium self-cleaning so some deadheading is advisable for best presentation. |
| Colour data and phenology |
Vibrant rich pink inner petals with silvery-rosy outer tones; buds vivid pink with crimson veining, flowers open deep pink then fade to soft pastel pink, with yellow stamens increasingly prominent in full bloom. |
| Fragrance and aroma |
No noticeable fragrance; the value lies in strong colour, large single blooms and open centres that support visual impact and pollinator access rather than scent-oriented positioning. |
| Hip characteristics |
Produces moderately abundant ovoid red hips, around 10–14 mm in diameter, offering modest late-season interest and potential value in wildlife-oriented plantings. |
| Resistance and winter hardiness |
Hardy to approximately -21 – -18 °C (USDA 6b, RHS H7, Swedish Zone 3); disease resistance is weak, with high susceptibility to powdery mildew and black spot and moderate rust sensitivity, requiring regular protection. |
| Horticultural recommendations |
Best used for pergolas, walls, solitary specimens and pillars; maintenance requirement is high with planned plant-protection programmes, and production is recommended as staked, trained climbers in 5–7 L containers. |
