Kardinal – Hybrid tea rose propagation material for professional production
Premium own-root Kardinal offers professional growers a stable propagation base for container and cut-flower oriented production where flower quality and exhibition-grade form are central. As a bush-trained hybrid tea with 3–5 strong framework canes it lends itself to uniform 5–7 L premium lines and structured nursery bed workflows, while own-root renewal supports homogeneous stands and low replacement over long cycles. The bushy, dense-foliage growth and mid-height frame combine well with collection and display settings, and its remontant habit underpins reliable repeat flowering for retail and reseller partners. In UK nursery conditions it fits integrated supply chains where winter and wind exposure are relevant across Scotland and northern England, providing a predictable, verifiable cultivar for thematic rose gardens and project-based ranges. Planned as tray-rooted, 3–6‑month-old material, it supports scalable scheduling from rooted cutting through to finished premium stock as roots establish in year one, framework builds in year two and full ornamental value stabilises by year three for wholesale and retail channels.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose ‘Kardinal’, registered cultivar name Kardinal, commercial type and group hybrid tea; current trade name Kardinal Hybrid tea rose Kardinal; ARS exhibition name Kardinal; unregistered in formal registration lists. |
| Origin and breeding |
Bred by Max Krause in Germany around 1933 from a ‘Château de Clos -Vougeot’ seedling; introduced commercially in 1936 via Hazlewood Bros. Pty. Ltd. in Australia; breeding institution data not provided beyond this attribution. |
| Awards and recognition |
not provided |
| Growth and structural characteristics |
Bushy hybrid tea shrub reaching approximately 75–105 cm in height with 60–85 cm spread; dense, slightly glossy light-green foliage (RHS 143C) and densely thorned shoots, supplied bush-trained on 3–5 strong structural canes. |
| Flower morphology |
Fully double, cupped, distinct mid-centred blooms carried mainly solitary; medium flower size around 1.5–2.75 in diameter, with 26–39 petals and a remontant habit that provides a plentiful second flowering flush under suitable management. |
| Colour data and phenology |
Deep coral-red hybrid tea, ARS DR, RHS 187A outer and 53B inner; buds fiery red–coral, warm coral when opening, then brick–terracotta tones before edges fade to rosy-powdery; overall medium colour retention with uniform intense coral-red at full bloom. |
| Fragrance and aroma |
Very weak fragrance with a neutral, clean character; not bred primarily for scent impact but for flower quality and form; double structure and discreet aroma mean olfactory contribution is limited in comparison with visually dominant bloom display. |
| Hip characteristics |
Hip set expected to be limited due to the fully double flower form; where present, spherical red hips of approximately 10–14 mm diameter can occur, but fruiting does not represent a defining ornamental or production feature. |
| Resistance and winter hardiness |
Moderate overall disease resistance, with powdery mildew, black spot and rust all rated moderate; cold tolerance to approximately –15 to –12 °C, RHS H6, Swedish Zone 2, USDA Zone 7b; heat and drought tolerance data not provided at this stage. |
| Horticultural recommendations |
Maintenance requirement medium, with occasional pest and disease control advised; recommended as a bush-trained plant with 3–5 canes, premium container route, 5–7 L target pot; primary uses and specific landscape roles not provided in the source. |
Kardinal combines exhibition-quality hybrid tea blooms, bush-trained structure and moderate input needs with the predictability and regeneration of own-root production, making it a reliable option for premium programmes where we can jointly plan capacity and scheduling.
