Casta Diva® Hybrid tea rose SELbar 0135 – pharmaROSA® NEONATAL
Purity in flower colour and an exclusive exhibition profile make Casta Diva® a focused choice for growers building premium white hybrid tea ranges on an own‑root base. As tray‑rooted pharmaROSA® NEONATAL material, these 3–6‑month‑old cuttings support predictable nursery scheduling from propagation bed to 5–7 L premium container production, integrating smoothly into UK nursery and public‑realm supply chains where reliable winter and wind tolerance is valued in northern regions. The pure white hybrid tea blooms, bred by Barni, are tailored for high‑specification borders, specimen plantings and cut flower lines in dedicated rose gardens and curated collections. While disease management needs to be rigorous, the cultivar’s defined form, dense foliage, and bushy habit translate into strong visual impact once established, particularly in thematic rose gardens and show collections. Own‑root physiology supports long‑term longevity under professional maintenance, with roots consolidating in year one, framework shoots building in year two, and full ornamental performance in year three for collection and premium retail programmes.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Casta Diva® Hybrid tea rose SELbar 0135 is a hybrid tea group cultivar for exhibition and cut flower use, with verified authenticity and premium silver internal quality rating for professional propagation. |
| Origin and breeding |
Bred by Vittorio Barni, Rose Barni S.r.l., Italy, with breeding work dated to 1982 and parentage listed as unknown; introduction and registration years are not provided for this cultivar. |
| Growth and structural characteristics |
Bushy plants reach about 80–100 cm in height with a 50–70 cm spread, carry moderately thorny shoots, and present dense, glossy light‑green foliage providing good leaf mass around the solitary blooms. |
| Flower morphology |
Large, solitary flowers are very full with 40+ petals, cupped with a pronounced mid‑height; they flower remontantly with an abundant second flush, but spent blooms require manual removal due to weak self‑cleaning. |
| Colour data and phenology |
Flowers are brilliant snow‑white across petals (ARS wh, RHS 155C outer, 155D inner), opening from milk‑white buds, retaining a cool white tone with minimal fading to a chalky white, without cream, yellow or pink tints. |
| Fragrance and aroma |
The cultivar is described as scentless with no noticeable fragrance character; its fully double form conceals stamens and does not contribute to pollinator attraction or aromatic applications. |
| Hip characteristics |
Moderate hip set with small, spherical red hips about 8–12 mm in diameter, contributing minor autumn interest but generally secondary to the primary flowering display. |
| Resistance and winter hardiness |
Hardy to approximately −21 to −18 °C (H7, Swedish zone 3, USDA 6b), but very susceptible to powdery mildew, black spot and rust, requiring high maintenance and regular plant protection in professional production. |
| Horticultural recommendations |
Best used as an exclusive finished product for borders, cut flower and specimen roles; advised route is bush‑trained premium container production in 5–7 L pots, with high maintenance and intensive disease management. |
Casta Diva® Hybrid tea rose SELbar 0135 combines exhibition-grade pure white blooms, a bushy, well-foliaged habit and long-lived, predictable own-root performance, offering a dependable premium option for which we would be pleased to align capacities and schedules with you.
