Irène Watts – historic salmon-pink China rose for professional own-root production
Historic shrub character, remontant flowering and compact sizing make Irène Watts a highly workable own-root option for premium, specialty lines in nursery propagation beds and 5–7 L container production. Its very full, cluster-flowered, salmon-pink blooms with a tea-scented, medium-intensity fragrance combine visual refinement with collector appeal for thematic rose gardens and curated ranges. On own roots, its renewal capacity supports long-term collection maintenance and stable, homogeneous stands with low replacement, well suited to UK nursery networks supplying public-realm and institutional projects in regions where winters are reliably tolerated and coastal wind exposure is manageable. With a medium maintenance profile and moderate disease tolerance, it slots efficiently into planned plant protection programmes for premium containers and border stock. In professional cycles, root establishment in the first year, structural shoot build-up in the second, and full ornamental value by the third year align predictably with capacity planning and wholesale scheduling for speciality and collector-focused ranges.

Data |
| Name and registration |
Irène Watts, Old garden rose collection, China/Bengale historic shrub; unregistered cultivar, current trade name Irène Watts Old garden rose Irène Watts, ARS exhibition name not provided. |
| Origin and breeding |
Seedling from ‘Madame Laurette Messimy’, bred by Pierre Guillot, Guillot & Fils Roseraie, France; introduced by Guillot & Fils in 1895, reflecting late 19th-century China rose selection. |
| Growth and structural characteristics |
Upright shrub, 60–100 cm high, 50–90 cm spread, moderately dense mid-green slightly glossy foliage (RHS 137A); densely thorned shoots, suitable for bush-trained use with discreet support where required. |
| Flower morphology |
Large, very full, cupped flowers with 40+ petals, produced in clusters; remontant, providing a plentiful second flowering flush, giving a long ornamental window for premium shrub and container production. |
| Colour data and phenology |
Soft salmon-pink newly opened flowers with creamy-yellow glow; fades through light and pastel pink to almost white outer petals; ARS pb, RHS 36C outer and 36D inner, colour retention good through flowering. |
| Fragrance and aroma |
Delicately sweet, tea-scented fragrance of medium intensity, clearly noticeable around the plant; double flower form limits pollinator access so value is primarily ornamental and sensory rather than ecological. |
| Hip characteristics |
Occasionally forms small spherical rose hips, 6–10 mm diameter, red RHS 53A; hip set is irregular, so decorative fruiting is a secondary feature rather than a primary production objective. |
| Resistance and winter hardiness |
Moderate resistance to powdery mildew, black spot and rust; tolerates heat well but needs watering in prolonged drought; hardy approximately to −15 to −12 °C, RHS H6, Swedish Zone 2, USDA Zone 7b. |
