Data |
| Name and registration |
Empereur du Maroc is a historic hybrid perpetual rose marketed as a historical rose; it is an unregistered variety used under its long‑established trade name in specialist and collector markets. |

| Awards and recognition |
not provided |
| Growth and structural characteristics |
Upright, bushy shrub reaching around 110–160 cm in height and 80–120 cm spread, densely thorned, with dense, mid‑green, matt foliage that clothes the framework well for structural planting roles. |
| Flower morphology |
Large, very double, rosette‑shaped blooms with 40+ petals, usually borne solitarily, offering the heavy, full flower form expected of hybrid perpetuals and supporting both specimen and cut‑flower uses. |
| Colour data and phenology |
Deep velvety dark crimson base that can shade to smoky violet‑black tones; colour stays deeper in cool conditions but may fade in sun and heat, with remontant flowering and a lighter second flush. |
| Fragrance and aroma |
Very strong, garden‑filling fragrance with a deeply spicy‑sweet character, giving a pronounced scent profile that is a central selling point for premium historic and collector‑oriented product lines. |
| Hip characteristics |
Hip set is generally scant due to the very double blooms; where formed, hips are ovoid, about 12–18 mm, orange‑red (RHS 34A), offering limited ornamental or harvest value in standard production. |
| Resistance and winter hardiness |
Rated resistant to powdery mildew, black spot and rust, with hardiness around −32 to −29 °C (RHS H7, Swedish zone 5, USDA 4b), but showing poor tolerance of prolonged heat or drought and needing watering. |
| Horticultural recommendations |
Suited to flower beds, specimens, cut use, and historic or collection gardens; best as bush‑trained with discreet support in premium or specialty containers, benefitting from regular watering in warmer settings. |
