Gruss an Heidelberg® Climbing rose KORbe – pharmaROSA® NEONATAL propagation material
Climbing production of Gruss an Heidelberg® as pharmaROSA® NEONATAL provides tray-rooted, own-root cuttings that support vertical feature lines for arches, pergolas, walls and fences in professional ranges. The cultivar’s carmine-red double, clustered, remontant blooms and upright, dense-foliaged structure make it a reliable specimen choice where an exclusive, space-defining finished product is required. With ADR-recognised performance and H7 winter hardiness backing medium-maintenance, medium-disease-resistance stands, it offers a robust framework for nursery propagation beds and trained climber programmes targeting 5–7 L containers. Own-root production supports long-lived, regenerating plants with stable ornamental value and low replacement needs, aligning well with UK nursery network logistics where reliable winter and wind tolerance is required across exposed northern projects. Building capacity from rooted cutting to trained, staked forms with 3–5 main canes allows you to plan a clear Year 1 roots, Year 2 shoots, Year 3 full ornamental value development arc for wholesale-scale collections and thematic ranges, underpinning wholesale-scale supply into retail and public-realm channels.

Hybrid of ‘World’s Fair’ × ‘Floradora’, bred by Reimer Kordes at W. Kordes’ Söhne, Germany; bred and introduced in 1959 in Germany as an unregistered cultivar for climbing use. |
| Awards and recognition |
ADR award (ADR-Sorte) Germany 1960, plus several American Rose Society Classic Shrub Rose exhibition awards from Mid-Michigan Rose Society, Thumb Rose Society and Olym shows. |
| Growth and structural characteristics |
Climbing habit with upright structure, 200–320 cm height, 120–200 cm spread; dense, glossy dark green foliage; densely thorned shoots; medium self-cleaning with some spent blooms needing manual removal. |
| Flower morphology |
Large, double, cup-shaped flowers with 26–39 petals; clusters on the shoot tips; remontant with an abundant second flush, providing repeated seasonal flowering for ornamental display plantings. |
| Colour data and phenology |
Carmine-red inner petal surfaces, paler rose-pink outer sides; colour lightens towards petal edges, shifting to rose-red while centres remain carmine; ARS colour code MR, RHS 46A and 53A references. |
| Fragrance and aroma |
Subtle rosy fragrance character with mild intensity; double, high-centred flowers largely cover the stamens, so pollinator attraction is low and the variety functions primarily as an ornamental rose. |
| Hip characteristics |
Hip formation usually low due to strongly double flowers; occasionally small, spherical red hips 6–10 mm in diameter may develop, but they do not generally dominate the ornamental effect. |
| Resistance and winter hardiness |
Medium overall disease resistance; resistant to powdery mildew and rust, medium against black spot; winter hardy to about -29 to -26 °C, corresponding to RHS H7, USDA Zone 5a and Swedish Zone 4. |
| Horticultural recommendations |
Suitable for arches, pergolas, walls, fences and specimen use; medium maintenance with occasional pest and black-spot management; ideal as staked, trained climber finished product in 5–7 L pots. |
