Henrietta – Hybrid tea rose – MACtexa
Exhibition quality hybrid tea on own roots, Henrietta offers a reliably upright framework with 3–5 strong canes, ideal for building premium container crops in 5–7 L formats and for disciplined bed and group planting programmes. Its very double, high-centred flowers deliver consistent cut-flower and specimen performance with repeat flushes, while stable ARS/RHS colour data and a distinctive yellow–red palette support clear catalogue positioning in exclusive finished-product lines. Dense, glossy dark-green foliage combines with documented resistance to black spot, mildew and rust to keep maintenance requirements low and crop presentation clean, aligning well with nursery networks supplying public and private collections in conditions comparable to Scotland and North England, where winter and wind tolerance are essential for dependable field and container production. On a professional timescale, you can plan for roots in year one, structural shoot development in year two and full ornamental value in year three, underpinned by the predictable, regenerative own-root base of the pharmaROSA® NEONATAL tray system for wholesale propagation and long-term stock security.
