ROSENTHAL – dark red hybrid tea rose - Kordes
Bring a sense of Cornish promenade glamour to your garden with Rosenthal, a velvety dark-red hybrid tea rose that feels as at home beside shingle and sea kale as it does in a town patio. Large, high-centred blooms on upright stems give you classic cutting-garden elegance for vases, while a strong, traditional rose fragrance creates a moment of pure indulgence with your afternoon tea. Bred on its own roots, this variety builds a dependable framework that shrugs off common rose diseases and offers reassuring long-term stability even in exposed spots where constant breezes and coastal showers demand secure anchoring and sensible drainage. It settles steadily over its first seasons, with roots in the first year, strong shoots in the second and a full display by the third, so you can simply relax and enjoy its endurance. In a generous 40–50 litre container on a veranda or in a mixed border, its compact yet substantial habit gives you rich colour without dominating the space, adding a thread of romantic continuity through the summer. Low maintenance, reliable and quietly luxurious, Rosenthal is made for busy gardeners who still want that “back from the beach, kettle on” feeling.
Usage options
| Target area | Reasoning |

Ideal for a 40–50 litre pot where its upright habit and dense foliage stay neat in confined spaces, while its strong roots offer reassuring grip in breezier, rain-lashed coastal weather for a sheltered seating nook; perfect for the busy veranda owner. |
| Small family front garden feature |
Compact height and contained spread let it act as a focal point near the front door without overwhelming paths, providing a clear, tidy structure you can rely on year after year with minimal reshaping; ideal for the time-pressed homeowner. |

| Long-season family border backbone |
Remontant flowering provides an early flush followed by a reliable second wave, giving a sense of continuity in mixed borders and helping the overall planting look “finished” over a long summer; suited to the family-garden planner. |
| Low-intervention rose planting for beginners |
Good resistance to black spot, mildew and rust means less spraying, fewer worries and a calmer gardening experience, so beginners can focus on watering and simple deadheading rather than complex routines; reassuring for the first-time rose grower. |
| Long-term specimen for stable structure |
As an own-root plant, it regenerates well from the base and maintains its named character over many years, building into a dependable, medium-sized rose that anchors a planting scheme gracefully; ideal for the long-view garden owner. |
