ROSENTHAL – dark red hybrid tea rose – KORtat

Imagine stepping into your own cottage corner of the garden, where the deep velvet blooms of this classic hybrid tea bring a sense of theatre to even an average family plot, while the bush itself remains compact and easy to place. With strong fragrance and long-stemmed, high-centred flowers ideal for the vase, Rosenthal bridges house and garden, giving you cut blooms without the fuss of specialist care. Bred by Kordes for robust health, it copes reliably with typical UK conditions, including breezier, wetter spots that often trouble other roses near the coast. As an own-root plant it offers dependable longevity, quietly rebuilding from its own wood after hard winters or accidental damage, so you can enjoy a stable display year after year. Low intervention maintenance and good disease resistance suit busy homeowners who want traditional romance rather than constant chores, while its upright habit fits mixed borders, narrow beds and larger containers from about 40–50 litres, settling gracefully into the garden picture over time.


Usage options

Target areaReasoning
Feature rose near a seating area or terrace The strong, classic rose fragrance of Rosenthal is best appreciated close to where you sit for afternoon tea or an evening drink, so a spot beside a bench, arbour or patio is ideal for turning everyday moments into small rituals for the scent-lover.
Cutting patch or kitchen-garden border Long-stemmed, high-centred flowers in a rich dark red make this variety naturally suited to cutting; plant a short row in a vegetable or cutting corner and you will have dependable, florist-style blooms to bring indoors for the home-arranger.
Romantic focal point in a small family garden Its upright, tidy habit and moderate height allow Rosenthal to stand out as a single specimen without swamping nearby plants, giving you a dramatic yet well-behaved centrepiece in limited space for the space-conscious.
Mixed cottage-style border with perennials The deep, velvety colour reads beautifully among light, frothy companions and classic cottage perennials, making it easy to weave into an informal planting scheme while keeping the structure and formality of a hybrid tea for the cottage-gardener.
Low-effort rose bed for busy households Good resistance to common rose diseases means less spraying and fewer problem checks, so a small group of Rosenthal can provide colour and scent with relatively few tasks through the season, suiting the time-poor.
Containers and large pots by the front door In a substantial planter of around 40–50 litres, this compact, upright hybrid tea forms a neat, glossy bush whose dark red blooms frame entrances and paths without outgrowing the space, making a welcoming statement for the urban-owner.
Exposed or breezier parts of the garden Bred with robust health and firm growth, Rosenthal tolerates the kind of rain and wind often met in more open or coastal gardens, keeping its foliage clean and blooms presentable for the weather-wary.
Long-term planting in a family plot As an own-root rose it can steadily rebuild and thicken over the years, giving reassuring longevity; expect roots to establish first, then stronger top growth, and only by the third season will it show its full ornamental presence for the patient-planner.

Styling ideas

  • Tea-table romance – Place Rosenthal by a small bistro set under an arbour, pairing it with Gypsophila ‘Festival Pink Lady’ in front for airy softness – for those who like to linger outdoors with a book.
  • Cottage ribbon – Thread several plants through a narrow border with evergreen candytuft at the edge, letting the dark red blooms rise from a white froth – for admirers of classic cottage borders.
  • Front-door welcome – Grow a single plant in a 50-litre terracotta pot, underplant with trailing ivy or seasonal herbs to dress the base – for homeowners wanting impact without redesigning the whole garden.
  • Kitchen-cutting strip – Line a sunny fence with Rosenthal, leaving space for rows of salad crops or herbs in front, giving easy access to long-stemmed blooms – for practical gardeners who love homegrown bouquets.
  • Evening retreat – Combine Rosenthal with soft grasses and pale pink perennials near a bench, where its strong scent and rich colour stand out at dusk – for those creating a quiet, reflective corner.

Technical cultivar profile
ParameterData
Name and registration Hybrid tea rose, registered as KORtat, marketed as Rosenthal Hybrid tea rose KORtat, with Tatjana accepted as the American Rose Society exhibition name.
Origin and breeding Bred by Reimer Kordes, W. Kordes’ Söhne, Germany, from ‘Liebeszauber’ × ‘Präsident Dr. H.C. Schroder’, introduced and registered in 1970 for garden and exhibition use.
Growth and structural characteristics Upright hybrid tea with dense, glossy dark green foliage, reaching about 70–95 cm in height and 50–70 cm spread, moderately thorny, forming a compact, well-branched bush.
Flower morphology Very double, high-centred, pointed-budded blooms with over 40 petals, solitary on stems, extra-large flowers around 3.5 inches across, remontant with a notably abundant second flush.
Colour data and phenology Deep, velvety dark red flowers; buds burgundy to near black, opening ruby-red with deeper centres, retaining colour well, with only slight fading or dulling in strong sun and hot conditions.
Fragrance and aroma Classic rose fragrance of strong intensity, clearly noticeable in the garden and on cut stems; very double form reduces stamen access, so it functions mainly as an ornamental rather than pollinator plant.
Hip characteristics Forms hips only in small quantities; ellipsoidal, about 10–14 mm in diameter, ripening to an orange-red shade, generally of minor ornamental impact compared with the flowers.
Resistance and winter hardiness Good resistance to powdery mildew, black spot and rust, reducing treatment needs; hardy to around −21 to −18 °C (RHS H7, USDA 6b), with moderate tolerance of heat and requiring watering in prolonged drought.
Horticultural recommendations Best in sunny positions with reasonably drained soil; spacing 50–90 cm depending on use, 2.8–3.2 plants/m² for massing; low maintenance needs, regular deadheading recommended for continuous, high-quality flowering.

ROSENTHAL – dark red hybrid tea rose – KORtat offers fragrant, long-stemmed blooms on a healthy, compact bush that matures steadily on its own roots; a thoughtful choice if you would like lasting romance with straightforward care.

Information about the videos
This video series is not a “seasonal showcase”, but a way of making the essence of own-root PharmaRosa® cultivation tangible: how the plant is structured, what the root system is like, and how the shoot system renews itself. The footage was therefore recorded at different times, showing plants at various stages of development, so mixed leaf cover or differing levels of development may appear in the videos. This is not a “sample” of the consignment delivered, but an illustration of how the technology works. The current condition of the rose You are purchasing, characteristic of the given period (the state in which You can expect to receive it in the parcel), is shown in the upper part of the product page.
