| Growth and structural characteristics |
Compact, upright, bushy shrub with 75–105 cm height and 45–75 cm spread; dense, slightly glossy mid-green foliage; moderately thorny; supplied bush-trained with 3–5 strong framework canes for structured growth. |
| Flower morphology |
Very double, XL-sized rosette flowers (3.5 in and above), 40+ petals, borne mainly in clusters of 3–5 per stem; remontant with plentiful second flowering; weak self-cleaning, requiring deadheading in finished production and landscape use. |
| Colour data and phenology |
Deep wine-red, raspberry-tinged blooms; buds deep raspberry–carmine; newly opened flowers vivid raspberry pink with wine-red flushes; full bloom medium-deep, velvety pink; colour fades to raspberry–powder pink with lighter edges. |
| Fragrance and aroma |
Medium-strength, noticeably scented flowers with a sweet, tea-like character; mainly ornamental, with double blooms that conceal stamens and limit pollinator access, so use where visual and fragrance value is prioritised over insect support. |
| Hip characteristics |
Produces small quantities of hips; spherical, dull red (RHS 46A), around 8–12 mm in diameter; hips are incidental to the primary ornamental and cut-flower value and are not a production focus. |
| Resistance and winter hardiness |
Moderate overall disease resistance; resistant to powdery mildew and black spot, moderate against rust; moderate heat and drought tolerance, requiring irrigation in prolonged dry spells; hardy to about -21–-18 °C, RHS H7, Swedish Zone 3, USDA 6b. |
| Horticultural recommendations |
Suitable for borders, specimen roles and cut flower use; medium maintenance with occasional plant protection; recommended as premium container product in 5–7 L pots; self-cleaning weak, so schedule deadheading in production and finished plant care. |
