Portofino™ NIRPATIO ADAmibros – pharmaROSA® NEONATAL rooted cutting
Miniature Portofino™ offers nursery and wholesale growers a compact, dwarf own‑root base for high‑turnover container and patio ranges, fitting smoothly into UK‑style integrated nursery systems that must cope with humid, fungus‑prone seasons and variable summers. Its compact 50–70 cm habit and 35–45 cm spread support dense benching and efficient tray logistics, while the remontant, clustered flowering delivers the “instant, long‑lasting floral display in a small space” that garden centres expect from exhibition mini roses. Cream‑white blooms with a fine pink edge and double 26–39‑petal cups present consistently in the 1.5–2 L “compact container – patio finished product” route, with medium self‑cleaning and moderate maintenance needs that remain manageable in retail nursery environments. Own‑root NEONATAL material underpins predictable renewal of plants and crop cycles, aligning with a development arc where roots stabilise in year one, shoots structure in year two and full ornamental value expresses from year three, supporting durable thematic and collection plantings for professional projects. With H7 hardiness down to -21 °C and resistant black spot behaviour, Portofino™ is a practical choice for repeated batch production and cultivar maintenance, while its sustainable own‑root form supports long‑term stocking and supply planning for UK nursery, garden centre and public‑realm oriented partners.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Miniature dwarf rose from the NIRPATIO collection, registered as ADAmibros and marketed as Portofino™ NIRPATIO ADAmibros, approved exhibition name Portofino for American Rose Society classes. |
| Origin and breeding |
Bred by Michel Adam in France, 2003, with parentage not provided; introduced commercially by Pépinières et Roseraies Adam with NIRP International noted as initial distributor, detailed registration year not provided. |
| Awards and recognition |
Not provided; no competition or show awards, collector recommendations, or wider lifetime distinctions are recorded for this cultivar in the available data. |
| Growth and structural characteristics |
Compact, dense bush 50–70 cm high and 35–45 cm across, moderately thorny shoots with dense, mid‑green slightly glossy foliage, forming a neat dome suited to containers, edging and low bedding schemes. |
| Flower morphology |
Small S‑size clustered blooms, 0.5–1.5 inches across, double‑flowered with 26–39 petals, cupped form; remontant habit providing an abundant second flush and extended seasonal colour in suitable conditions. |
| Colour data and phenology |
Cream‑white base with pale pink margins, ARS wb; RHS 155D outer, 65C inner, buds with subtle pink tips, colour fading toward uniform off‑white in sun as pink edging lightens, with moderate overall colour retention. |
| Fragrance and aroma |
Very weak, barely detectable fragrance with a soft rosy character; double blooms moderately accessible to pollinators, so overall pollinator value is limited compared with simpler flower forms. |
| Hip characteristics |
Produces red, spherical hips approximately 6–10 mm in diameter, expected in moderate quantities, adding some late‑season visual interest in collection or reference plantings where hips are retained. |
| Resistance and winter hardiness |
Hardy to around -21 to -18 °C, RHS H7, Swedish Zone 3, USDA 6b; disease resistance moderate overall with black spot resistant behaviour and moderate susceptibility to powdery mildew and rust, needing occasional protection. |
| Horticultural recommendations |
Recommended for containers, flower beds, edging and terraces; medium maintenance needs with some self‑cleaning but periodic deadheading, responding well to compact container production and patio‑focused retail concepts. |
