Corona hybrid tea rose – pharmaROSA® NEONATAL rooted cutting
Corona offers a premium own-root propagation base for nurseries aiming at exclusive cut-flower and specimen-grade container production, where strong flower quality and rosette form are core selling points in retail and reseller channels. As a dense, upright hybrid tea with XL blooms and high petal count, it supports bush-trained release forms with 3–5-cane framework, ideal for a 5–7 L premium container route and later step-up into 40–50 litre feature plant units for high-impact thematic collections. Strong, long-lasting fragrance and warm coral-pink tonality underpin positioning in curated display benches and show-garden style borders, while H7-rated hardiness provides reassurance for UK nursery networks operating in cooler, more exposed areas where winter and wind tolerance support consistent field and container performance. As own-root pharmaROSA® NEONATAL material, Corona allows predictable build-up of homogeneous stock, with root mass in year one, structural cane development in year two, and full ornamental expression from year three, aligning well with longer planning horizons for professional rose production.

| Origin and breeding |
Bred by Junko Kawamoto at Kawamoto Rose Garden, Japan; parentage unknown; breeding year and introduction both 2010; initial distribution via Kawamoto Rose Garden; registration year data not available. |
| Awards and recognition |
Awards, competition results and collectors’ recommendations are not provided, and there are no documented global or lifetime honours; horticultural rating data and show successes are currently not provided. |
| Growth and structural characteristics |
Upright hybrid tea shrub reaching approximately 90–130 cm in height with 80–120 cm spread; moderately thorny shoots; dense, dark green, slightly glossy foliage; self-cleaning behaviour not documented; suited to bush-trained forms. |
| Flower morphology |
Double, rosette-shaped blooms with 26–39 petals; XL flower size from about 3.5 inches upwards; flowers mainly borne singly rather than in clusters; remontant, with abundant second flush flowering under suitable cultivation and care. |
| Colour data and phenology |
Warm coral-toned pink with subtle salmon hue; ARS code op, RHS 36B outer and 36C inner; emerging buds deep saturated coral pink; blooms lighten with opening and may show greenish tinge in heat; poor colour retention in strong conditions. |
| Fragrance and aroma |
Described as strongly scented with long-lasting fragrance; detailed scent character notes are not provided; double, rosette form limits stamen access and therefore pollinator attraction, so the variety is primarily ornamental rather than ecological. |
| Hip characteristics |
Rose hip set expected to be low because of the double flowers; when formed, hips are small globular spheres, around 6–10 mm in diameter, coloured red to orange, and generally of limited ornamental or production significance. |
| Resistance and winter hardiness |
Hardy to approximately –26 to –23 °C, RHS H7, roughly USDA Zone 5b and Swedish Zone 4; very susceptible to powdery mildew and black spot, moderate susceptibility to rust; in hot weather, flower shape may deteriorate; drought data not provided. |
| Horticultural recommendations |
Primary uses include borders, containers, cut flower and specimen roles; best for premium container production with bush-trained forms and 3–5 framework canes; disease management needs to be intensive due to high susceptibility; maintenance requirement high. |
