White Swan – pharmaROSA® NEONATAL rooted cutting for professional production
Exhibition performance and purity of bloom make White Swan a dependable choice where high-end hybrid tea presentation matters, while its remontant flowering and good self-cleaning support efficient, premium container scheduling in 5–7 L formats. Upright structure with moderately dense, mid‑green foliage gives a clean, classical bush-trained outline on 3–5 framework canes, suitable for exclusive finished products and cut-flower oriented ranges. Own-root production provides long-term stability and regenerative capacity, reducing replacement rates and supporting homogeneous stands under repeated cutting and pruning. In typical UK nursery systems it offers reliable winter performance with hardiness rated to H7, useful for networks servicing cooler, wind-exposed regions where dependable outdoor field and container culture are required. Over a normal development arc roots consolidate in year one, framework and flowering volume build in year two, and full ornamental impact is reached by year three, supporting predictable crop planning for retail/reseller-focused programmes and thematic rose collections. The restrained tea fragrance and controlled growth habit make it an adaptable component for curated white collections and project palettes, while the pharmaROSA® NEONATAL tray-rooted format underpins scalable supply and integration into existing logistics workflows for nurseries and wholesale partners.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose marketed as White Swan, with ARS exhibition name White Swan and commercial presentation as White Swan hybrid tea rose; unregistered variety traced to mid-twentieth-century breeding. |
| Origin and breeding |
Bred in the Netherlands in 1951 by Hendrikus Antonie Maria Verschuren from ‘Kaiserin Augusta Viktoria’ crossed with an unknown white seedling, introduced in 1952 via Jackson & Perkins Co. in the USA. |
| Growth and structural characteristics |
Upright hybrid tea habit reaching around 80–105 cm in height with a 50–70 cm spread, moderately dense mid‑green foliage and moderate prickliness, forming a clear bushy outline when trained on 3–5 framework canes. |
| Flower morphology |
Double, high-centred, cut-rose type blooms with 26–39 petals, medium flower size in solitary arrangement, producing classic pointed buds well suited to exhibition and cut-flower style presentations in garden contexts. |
| Colour data and phenology |
Flowers open creamy white and mature to a pure, bright snow-white without yellow or pink tones; colour is long-lasting, fading only slightly, with some translucence before fading, and uniform whiteness on petal undersides. |
| Fragrance and aroma |
Soft, tea-scented fragrance of mild intensity, giving a restrained aromatic presence that supports close-planting in borders and specimen displays without dominating nearby plantings or scented features. |
| Hip characteristics |
Occasionally forms small, spherical orange-red hips around 10–14 mm in diameter, adding limited seasonal interest but generally secondary to the plant’s primary role as a flower-focused hybrid tea cultivar. |
| Resistance and winter hardiness |
Moderate resistance to powdery mildew, black spot and rust; heat tolerance good with limited drought data; hardy to approximately −21 to −18 °C, corresponding to RHS H7, Swedish zone 3 and USDA zone 6b. |
| Horticultural recommendations |
Best used as border, cut-flower and specimen plant; medium maintenance with occasional pest and disease control; ideal as bush-trained own-root stock in 5–7 L premium containers from pharmaROSA NEONATAL rooted cuttings. |
White Swan offers pure white, exhibition-style blooms, upright container-suitable structure and own-root longevity that stabilises production and stocking; it is a practical option to discuss for aligned capacity and delivery planning.
