DU CHÂTELET – pink nostalgic rose – pharmaROSA NEONATAL
Romantic own-root propagation material of DU CHÂTELET gives nurseries a reliable basis for premium container production where flower quality and nostalgic form are central. This bushy, dense-foliaged cultivar builds a compact, exhibition-grade framework well suited to 5–7 L premium containers and exclusive ranges for retail and reseller partners. Its remontant, large, cluster-flowered heads and pastel-pink, award-winning blooms support positioning in thematic rose gardens and curated collections, while own-root longevity allows planting for flowerbeds, parks and specimen roles with lower replacement pressure. The variety’s medium maintenance profile is manageable within UK nursery networks that must plan for wind-tolerant, winter-hardy performance in Scottish and northern schemes, and it responds well to bush-trained release with 3–5 strong canes. Year by year, roots consolidate first, then shoots structure, then full ornamental impact stabilises, helping You schedule reliable, repeatable output into exclusive ranges and project-based programmes.

| Awards and recognition |
Recognised with multiple international distinctions including Baden-Baden silver medal and honorary award, Rome and Buenos Aires medals, and certificates of merit from Saverne and Orléans, confirming strong ornamental and show value. |
| Growth and structural characteristics |
Bushy shrub 80–120 cm high and 55–90 cm wide, with dense, slightly glossy dark green foliage and moderate prickliness; forms a solid structural framework suited to bush training on 3–5 main canes in container or bed production. |
| Flower morphology |
Large, very double, globular to pompon flowers with over 40 petals, borne mainly in clusters, providing a pronounced Romantic effect; remontant habit with an abundant second flush supports high ornamental impact through the main season. |
| Colour data and phenology |
Delicate pastel pink, ARS lp, RHS 65C outer and 65D inner; buds are silky light pink, blooms powder-pink with subtle carmine tints, fading gradually to very pale, almost whitish pink as flowers mature, giving soft tonal variation in plantings. |
| Fragrance and aroma |
Fragrance is mild with a delicate, light character, adding refinement without overwhelming display areas; floral scent presence is noticeable at close range, supporting premium positioning without demanding fragrance-led marketing claims. |
| Hip characteristics |
Hip set is expected to be low due to very double flowers; where formed, hips are spherical, around 9–15 mm in diameter and orange-red, offering modest visual interest without significantly affecting flowering performance. |
| Resistance and winter hardiness |
Medium resistance to powdery mildew, black spot and rust; performs moderately in heat and needs irrigation in prolonged drought. Hardy approximately to −21 to −18 °C, matched to RHS H7, suitable for many temperate and cooler production zones. |
| Horticultural recommendations |
Recommended for flowerbeds, parks and as a specimen shrub, with medium maintenance including periodic pest and disease control; best marketed via premium container production, bush-trained on 3–5 strong canes for high-quality retail presentation. |
