Tourmaline™ Hybrid tea rose DELfri – pharmaROSA® NEONATAL rooted cutting
Flower quality and high-centred, cut-rose type form make Tourmaline™ a convincing choice where exhibition-level hybrid tea presentation supports premium container ranges and exclusive finished product assortments. Its remontant repeat flowering with abundant second flush enables you to plan longer retail availability from 5–7 L premium container programmes, while the upright, bush-trained habit with 3–5 strong framework canes delivers consistent plant architecture for homogeneous benches. Own-root production provides predictable regeneration and lifespan under nursery propagation and grow-on, supporting stable capacity, low replacement and reliable stock for thematic rose gardens and curated collections. With moderate disease resistance including resistance to powdery mildew and black spot, it aligns well with UK nursery and reseller expectations where dependable performance across cooler, potentially wind-exposed regions is valued for long-term project planting. Medium maintenance requirements and manageable, moderately thorny canes help streamline crop care, while the controlled 100–140 cm plant height fits premium container, retail and reseller positioning for high-value hybrid tea cut-flower style garden roses.
