Sibelius – violet-purple park rose – pharmaROSA® NEONATAL rooted cutting
shrubs from pharmaROSA® NEONATAL offer professional growers a stable, own-root base for producing retail-ready park material, and Sibelius delivers a compact, bushy structure that works efficiently in standard container production. Its clustered semi-double blooms, remontant habit and reliable violet-purple colour dynamics support an attractive, recognisable finished product with strong consumer garden performance. Own-root material underpins long-term stands with predictable growth and reduced replacement, well suited to nursery propagation beds and 2–3 L routes into the retail/reseller channel. Over years of cropping, roots establish first, structural shoots follow, and full ornamental impact consolidates by the third season, making it a sound option where wholesale partners seek dependable volumes for public-realm schemes in cooler regions with robust winter tolerance supporting exposed sites.
