Herkules ® MärchenRosen® KORherkul – pharmaROSA® NEONATAL rooted cutting for professional production
With its Romantic nostalgia aesthetic, premium flower form and lavender colour nuance, Herkules ® MärchenRosen® KORherkul offers professional growers a distinctive shrub rose for high-value, exclusive containers. The dense, dark foliage, bushy framework and 3–5-cane bush-trained release form support uniform premium container production in 5–7 L, aligned to retail and reseller channels focused on flower quality and form. Own-root NEONATAL material gives a renewable, long-lived base that supports predictable development: roots consolidated in year one, structural shoots in year two, and full ornamental value from year three onwards. The variety’s remontant, very double flowers with strong, fruity fragrance are well suited to thematic rose collections and show gardens, while its hardiness profile supports planning for Scottish and northern English schemes where winter and wind resilience is required.
