Rosomane Janon Générosa® MASjanon – pharmaROSA® NEONATAL rooted cutting
Générosa® own-root propagation of Rosomane Janon provides a stable, premium shrub base for nursery and wholesale systems aiming at exclusive nostalgic production. As a nostalgia shrub with XL, very double rosette blooms and strong colour play from cream-yellow to warm pink, it is a reliable choice where flower quality and form drive value. Bush-trained NEONATAL cuttings form 3–5 strong framework canes, ideal for a 5–7 L container route into retail / reseller channels, with consistent height and moderately dense foliage to support high-end presentation. Own-root structure underpins long-term productivity and predictable renewal in propagation beds, with year-one root establishment, year-two shoot build-up and year-three full ornamental delivery, aligning well with UK nursery cycles and supporting projects where winter and wind tolerance suits exposed northern sites. Medium-strength, fruity fragrance and cut-flower suitability round out a versatile profile for thematic rose collections and park borders.
