Dany Hahn Générosa® MAShahn – pharmaROSA® NEONATAL rooted cutting
The Dany Hahn Générosa® MAShahn shrub offers a premium own-root propagation option for nurseries building exclusive, nostalgia-style ranges where flower quality and romantic form matter as much as predictable field performance. As a Romantica shrub in the Générosa® collection, it fits smoothly into premium container programmes, especially when bush-trained with 3–5 strong canes for 5–7 L pots and larger. Its upright habit, dense mid-green foliage and 120–160 cm height support clear, marketable structure in beds, borders and specimen uses, while remontant, very double, cluster-flowered peach blooms with warm apricot to pale salmon-pink tones deliver consistent impact for high-value retail and reseller channels. Own-root production supports long-term stability, homogeneous stands and low replacement rates under repeated propagation loads, giving You reliable capacity planning. In harsher UK settings You benefit from its H7 hardiness and USDA 5a rating, offering dependable winter hardiness for Scottish and northern schemes exposed to cold and wind, while the development from root establishment in year one to structural shoots in year two and full ornamental expression from year three onwards supports phased programming of premium collections in thematic rose gardens and show gardens.
