SUSAN MASSU® – yellow-pink hybrid tea rose – KORad
Premium own-root pharmaROSA® NEONATAL material of SUSAN MASSU® provides a stable propagation base for nurseries needing reliable, exhibition-grade flowers and consistent hybrid tea form in 5–7 L premium containers. The upright, bush-trained framework with 3–5 strong canes supports uniform crop architecture and predictable height for border, specimen and cut-flower orientated production, while dense, glossy dark green foliage delivers a finished product with strong visual impact for exclusive retail and reseller channels. Medium-strength, pleasantly sweet fragrance, large, high-centred solitary blooms and verified cultivar authenticity underpin professional-grade quality for thematic rose gardens and collection plantings. Own-root stock supports renewable growth, long lifespan and low replacement in nursery beds and container systems, well suited to UK-wide supply where winter and wind tolerance is important, and aligning with a planned development arc from roots in year one through structural shoots in year two and full ornamental value by year three. With medium maintenance needs and occasional pest control, SUSAN MASSU® can be integrated efficiently into premium-range production programmes and private-label offerings focused on exhibition hybrid tea quality and credibility in exclusive finished products for wholesale partners.
