Stella Polare hybrid tea rose TANlarpost – pharmaROSA® NEONATAL
With its exhibition-grade, high-centred white blooms and proven cut-flower pedigree, Stella Polare TANlarpost offers a premium route into own-root hybrid tea production for nurseries targeting exclusive, high-value ranges. The bushy, upright habit with glossy, dark green foliage supports a disciplined, 5–7 L container programme, ideal where bench and standing space must convert predictably into retail-ready stock. This cultivar’s remontant, solitary flowers and excellent colour retention allow you to plan a premium cut-flower and specimen offer that keeps its snow-white clarity through the entire sales window, even in mixed nursery light conditions. On own roots, the long-term structural stability and capacity for regeneration underpin homogeneous stands, lower replacement and dependable capacity for thematic rose gardens and collection projects. Professionally bush-trained with 3–5 strong framework canes, it is well aligned to a borders and patio-focus route where consistent flower form and height matter more than mass planting density. The moderate maintenance profile, with medium self-cleaning and occasional deadheading, suits UK nursery labour realities while supporting a refined specimen positioning at retail and reseller level. Once established, own-root stock builds from root development in year one, through canopy and framework consolidation in year two, into full ornamental and production value in year three, matching longer-term planning horizons for public and institutional projects. Its tested hardiness to H7/USDA 4b offers reassurance for networks serving colder regions and exposed schemes, quietly reinforcing professional credibility in demanding climates such as northern and upland sites where winter and wind tolerance is a practical necessity for reliable supply. In this way, Stella Polare TANlarpost becomes a robust, renewable asset within integrated UK nursery and wholesale production systems focused on exclusive finished product.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose group; registered as TANlarpost, traded as Stella Polare Hybrid tea rose TANlarpost, with Polarstern as the ARS approved exhibition name, supporting clear identification in trade documentation. |
| Origin and breeding |
Bred by Mathias Tantau Jr. in Germany (1982), introduced by Wheatcroft Brothers Ltd. in the United Kingdom in 1984; parentage is unknown but performance has been proven in European and North American conditions. |
| Awards and recognition |
Rose of the Year and RNRS Certificate of Merit in the United Kingdom in 1985, plus several regional ARS awards across North America between 1998 and 2012, underlining longstanding exhibition and garden performance value. |
| Growth and structural characteristics |
Bushy habit to around 85–120 cm high and 70–95 cm spread, with moderately dense, dark green glossy foliage and moderate prickliness; spent blooms need occasional deadheading due to medium self-cleaning behaviour. |
| Flower morphology |
Large, double, high-centred flowers with 26–39 petals, solitary on stems and clearly in the modern cut-rose type; remontant, with abundant second flowering, suitable for exhibition-quality cut and premium pot display. |
| Colour data and phenology |
Pure white throughout development (ARS W; RHS 155C outer, 155D inner), with only faint creamy tones at the claws; colour holds excellently with hardly any fading, maintaining an immaculate, luminous white at full bloom. |
| Fragrance and aroma |
Mild but distinct, with a fresh, lively character that complements the clean white bloom; primarily ornamental in function, as the double flower structure encloses the stamens and limits pollinator access. |
| Hip characteristics |
Hip set is generally low due to the double flower form; where present, hips are small, egg-shaped, orange-red and around 10–14 mm in diameter, with limited visual impact on the overall ornamental effect. |
| Resistance and winter hardiness |
Hardy to approximately -32 to -29 °C (H7, USDA 4b, Swedish Zone 5), with black spot resistance and moderate tolerance to powdery mildew and rust; heat and drought tolerance is moderate, needing watering in dry spells. |
| Horticultural recommendations |
Suited to borders, cut flowers, specimen and container-grown production; medium maintenance with occasional plant protection and deadheading, best routed as premium container stock, bush-trained with 3–5 strong canes. |
Stella Polare TANlarpost combines exhibition-grade white blooms, robust cold hardiness and a bushy, container-suited habit on a predictable, regenerative own-root base; we would be pleased to discuss volumes, timelines and alignment with your production plans.
