Tresor du Jardin – pharmaROSA® NEONATAL rooted cutting for professional production
Exhibition performance, fragrance intensity and refined colour make Tresor du Jardin a compelling choice where cut-flower and premium container hybrid tea production must justify a clearly higher price point and selective placement. As own-root material, pharmaROSA® NEONATAL cuttings provide a renewable structural base that supports long-term cropping and stock-plant programmes with predictable vigour and reduced replacement over time. In typical UK nursery and integrator systems, these tray-rooted young plants slot efficiently into bush-trained, 3–5-cane lines for 5–7 L premium containers, while still allowing selected stems to be directed towards the cut-flower and exhibition category. Over the first seasons, roots establish, then framework shoots strengthen, and by the third year full ornamental and cutting value stabilises, helping you maintain homogeneous, high-impact blocks even in projects exposed to winter and wind across northern sites. In this way, you can confidently align exclusive-finish scheduling and retail/reseller expectations with a cultivar bred for high-end presentation, outstanding flower form, strong fruity aroma and consistent quality at commercial scale.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose, registered as ADAloriat, marketed as Tresor du Jardin within the NIRPARFUM collection; approved exhibition name Tresor du Jardin for show and cut-flower categories. |
| Origin and breeding |
Bred by Michel Adam in France, breeding year 2013; introduced in 2014 by NIRP International, with parentage not provided and targeted towards high-end hybrid tea performance. |
| Awards and recognition |
Extensively awarded in 2015: Baden-Baden Goldene Rose, Gold Medal hybrid tea, Fragrance Award, Aesthetic Jury and Breeder's Jury first prizes, plus Lyon “Plus Belle Rose de France” distinction. |
| Growth and structural characteristics |
Compact, upright bush reaching approximately 60–90 cm in height with 45–65 cm spread; dense, dark green glossy foliage and moderate prickliness; self-cleaning behaviour not provided. |
| Flower morphology |
Large solitary blooms, 2.75–3.95 in, very double with 40+ petals; cupped shape with a pronounced, medium-high centre; remontant with notably abundant second flowering flush after the first. |
| Colour data and phenology |
Delicate cream-pink tonality, ARS code LP, RHS 155D and 36D; buds pale cream with pink tips, opening to cream-white outer petals and pastel pink inner tones, fading gradually to near-white before senescence. |
| Fragrance and aroma |
Strong, clearly perceptible fruity fragrance character; very full flowers can limit direct stamen access, so pollinator value is moderate despite scent; fragrance suitable where aroma is a key selling feature. |
| Hip characteristics |
Produces a moderate quantity of ovoid, orange-red hips, approximately 12–18 mm in diameter; hips contribute to later-season ornamental interest where flowers have diminished. |
| Resistance and winter hardiness |
Hardy to approximately -21 to -18 °C, RHS H7, USDA 6b, Swedish zone 3; very susceptible to powdery mildew, black spot and rust, requiring rigorous, regular pest and disease management in production. |
| Horticultural recommendations |
Suited to flower beds, specimen use and cut-flower production; recommended as a bush-trained plant with 3–5 strong framework canes for premium container routes; maintenance requirement high, with low innate disease resistance. |
Tresor du Jardin ADAloriat offers exhibition-level flower form, strong fragrance and remontant performance on a predictable own-root base, making it a considered option for exclusive premium container lines where we can jointly plan capacity and scheduling.
