GRÄFIN DIANA® – burgundy-red hybrid tea rose – KORdiagraf
Parfuma selection GRÄFIN DIANA® brings fragrance-driven, exhibition-grade flower quality into a professional own-root format designed for nursery-scale propagation and premium container production. As a pharmaROSA® NEONATAL tray-rooted cutting, it offers a uniform, bush-trained starting point with 3–5 future framework canes for tight batch scheduling and predictable development in 5–7 L premium containers, and can later be stepped up into 40–50 litre display specimens for top-end retail and show-garden installation. Its deeply coloured, velvety, burgundy-red hybrid tea blooms suit premium cut-flower and solo-feature positioning where high-intervention plant protection is already standard practice, especially within thematic or collection rose gardens supplied by UK nursery networks that also serve wetter, disease-prone western regions through careful crop management. Own-root structure underpins long-term regeneration and stable stands, aligning with professional capacity planning across multi-year production. In practice, you see the root system consolidate in the first year, strong structural shoot building in the second, and full ornamental expression from year three onwards – supporting reliable, repeatable high-end colour and scent in your offer.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose, registered as KORdiagraf, marketed as Gräfin Diana® Parfuma®, an exhibition hybrid tea and premium cut-flower type with verified cultivar authenticity for professional propagation. |
| Origin and breeding |
Bred by Tim-Hermann Kordes (W. Kordes’ Söhne, Germany), introduced and registered in 2012, from Chartreuse de Parme × (Esther Geldenhuys × unknown seedling), aligning with modern fragrant breeding lines. |
| Awards and recognition |
Holds ADR Germany 2014, Rose des Jahres GRF 2017, Grand Prix de la Rose France 2018, and multiple first-place fragrance awards in The Hague and Adelaide, underpinning its fragrance and garden merit claims. |
| Growth and structural characteristics |
Upright, bushy, slightly columnar habit reaching 100–140 cm high and 65–95 cm spread, with dense, glossy dark green foliage and moderate prickliness, forming a strong visual structure in premium containers. |
| Flower morphology |
Very double, rosette-shaped hybrid tea blooms with 40+ petals, large flower size on mainly solitary stems, well remontant with abundant second flowering, though with only moderate self-cleaning of spent blooms. |
| Colour data and phenology |
Deep, velvety burgundy-red with subtle black tones, ARS code DR, RHS 60A outer and 53B inner; colour holds well, becoming slightly paler in heat and deeper in cool weather, fading to ruby red without browning. |
| Fragrance and aroma |
Very strong, garden-filling fragrance with a fruity, spicy character, selected for ornamental and sensory impact; heavily double blooms conceal stamens, limiting pollinator access and focusing on human scent appeal. |
| Hip characteristics |
Due to the very double flowers, rosehip formation is limited, with occasional small spherical orange-red hips 6–10 mm in diameter, so hips are not a primary ornamental or propagation feature in production. |
| Resistance and winter hardiness |
Rated very susceptible to powdery mildew, black spot and rust, requiring high-maintenance plant protection; winter hardy to around –21 to –18 °C, RHS H7, corresponding to USDA Zone 6b and Swedish Zone 3. |
| Horticultural recommendations |
Best used where flowerbed, cut-flower, specimen and fragrant garden value justify intensive care; suited to premium container routes from bush-trained NEONATAL stock with regular interventions and disease control. |
GRÄFIN DIANA® combines award-winning fragrance, exhibition-grade flower quality and own-root longevity into a predictable, renewable premium line; consider aligning capacity and scheduling to integrate this Parfuma cultivar into your high-end offer.
