FLORENTINA ® – dark red climbing rose - Kordes – pharmaROSA® NEONATAL
Exclusive own-root pharmaROSA® NEONATAL material of Florentina® Klettermaxe® KORtrameilo offers a reliable base for professional climber production where vertical features and cultivar authenticity matter long term. As a large-flowered climber with dense, glossy foliage and premium dark-red blooms, it is well suited to pergolas, arches, pillars and wall-training in thematic show gardens and public-realm schemes, including demanding sites with winter and wind exposure where dependable hardiness is valued. Its ADR-certified resistance, zoned to USDA 5b and RHS H7, supports low-input nursery systems and reduces quality fluctuations across networks. Own-root structure underpins longevity and regeneration, helping You maintain homogeneous stands and predictable capacity over repeated cropping cycles. Supplied as tray-grown, staked and pre-trained 3–6‑month NEONATAL cuttings with 3–5 main canes, it integrates efficiently into trained climber lines in 5–7 L containers and can be stepped up into 40–50 L statement units for institutional ranges. With low maintenance requirements, good heat and drought tolerance, and scant hip set to preserve ornamental value, the development from root establishment in year one, structural cane building in year two and full ornamental performance from year three aligns well with UK nursery scheduling. This combination of award-winning performance, premium presentation potential and sustainable own-root propagation makes Florentina® a strong option for nurseries, integrators and wholesalers building differentiated vertical rose offers.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Large-flowered climbing rose registered as KORtrameilo, marketed as Florentina® Klettermaxe® KORtrameilo, with American Rose Society exhibition name Florentina; exhibition-suitable yet also strongly oriented to garden display. |
| Origin and breeding |
German-bred by Tim-Hermann Kordes at W. Kordes’ Söhne, from unnamed seedling crosses; bred 2002, registered 2012 and introduced after 2012 through W. Kordes’ Söhne and partners for international climber markets. |
| Awards and recognition |
Internationally recognised with Buenos Aires Gold (2012), Tokyo International Great Rose Show Silver (2013), ADR certification in Germany (2016) and “Best of the Best” at La Tacita International Rose Competition in Italy (2016). |
| Growth and structural characteristics |
Climbing habit reaching 200–300 cm in height with 70–130 cm spread, dense dark green glossy foliage (RHS NN137A) and densely thorned canes; supplied staked and pre-trained with 3–5 main canes for structural training. |
| Flower morphology |
Large, very double rosette blooms with 40+ petals, typically borne in corymbose clusters; remontant flowering with strong first flush and lighter second bloom, providing showy, large-flowered climber presentation for structures. |
| Colour data and phenology |
Vivid, saturated dark red flowers (ARS dr, RHS 46B) from deep crimson buds; colour holds well then fades towards pinkish-purple, with a barely visible whitish eye at full bloom, maintaining decorative value over the opening phase. |
| Fragrance and aroma |
Mild, delicately rose-scented fragrance complementing the visual effect without dominating; very double flower form encloses stamens, giving limited pollinator value and focusing the cultivar’s role on ornamental display and structure. |
| Hip characteristics |
Hip set is generally scant due to the very double blooms; occasional spherical hips 10–15 mm in diameter may form, coloured orange-red (RHS 40A), with little impact on overall ornamental or production performance. |
| Resistance and winter hardiness |
High resistance to powdery mildew, black spot and rust; hardy to approximately −26 to −23 °C (RHS H7, Swedish zone 4, USDA 5b), with good heat tolerance and irrigation needs only under prolonged drought conditions. |
| Horticultural recommendations |
Best used as a low-maintenance climber on pergolas, fences, arches, pillars and walls, also suitable for cutting; prefers trained-climber production in 5–7 L and larger pots, with moderate self-cleaning and some deadheading required. |
