Shioli – Romantic rose shrub for premium own‑root production
Romantic Shioli offers a refined, nostalgic flower form with a soft pastel pink and cream palette, well suited to premium container production where flower quality is the leading sales argument. As pharmaROSA® NEONATAL own‑root material, it provides a stable base for nursery networks aiming at exclusive finished product ranges, with tray‑rooted cuttings at 3–6 months that are easy to schedule into 5–7 L premium containers. The bushy habit with slightly arching shoots and dense, dark green, slightly glossy foliage supports visually homogeneous stands for retail and reseller programs. Medium disease resistance with listed strengths against powdery mildew and black spot limits intervention needs to occasional, targeted crop protection. The gently remontant, very double rosette blooms deliver a plentiful second flush, underpinning a reliable flowering window for collection and thematic rose garden projects. Own‑root production encourages long lifespan, regeneration and low replacement in stock fields, and the development arc from stronger roots in the first year through structural shoots in year two to full ornamental expression in year three helps align your capacity with exclusive finished‑product positioning. With hardiness rated H7 and USDA 6b, it adapts well to UK nursery sites, performing reliably even in colder, more exposed Scottish and northern locations where winter and wind performance are important considerations.

| Awards and recognition |

| Growth and structural characteristics |
Bushy shrub, 75–100 cm high with 60–85 cm spread and slightly arching shoots; moderately thorny, dense, dark green, slightly glossy foliage delivers a compact, well-furnished framework under bush-training. |
| Flower morphology |
Large, very double rosette blooms with over 40 petals, borne mainly solitary; remontant habit produces a plentiful second flush, supporting an extended flowering phase under appropriate cultural management. |
| Colour data and phenology |
Soft pastel pink with a subtle cream undertone; buds cream-white with pink tips, opening powder pink with creamy centre, then fading through restrained pale pink to almost white; RHS 65C outer and 158D inner zones. |
| Fragrance and aroma |
Exhibits a delicate, floral fragrance described as very weak and barely noticeable, so scent is present but not a dominant sales feature; heavily double form limits appeal as a pollinator-focused planting choice. |
| Hip characteristics |
Hips form only occasionally due to the double blooms; where present they are small, 8–12 mm, globe-shaped and orange-red, offering minor seasonal interest without materially affecting production planning. |
| Resistance and winter hardiness |
Medium overall disease resistance with resistance to powdery mildew and black spot, medium rust susceptibility; hardy to around -21–-18 °C, corresponding to RHS H7, Swedish zone 3 and USDA zone 6b for cold exposure. |
| Horticultural recommendations |
Recommended as a premium container shrub rose, bush-trained with 3–5 strong framework canes in 5–7 L pots; maintenance is medium, with occasional pest and disease control advised to retain optimum presentation quality. |
Shioli combines premium Romantic bloom quality, compact bushy structure and documented hardiness with the predictability and regeneration of own-root NEONATAL material, making it a sound candidate for exclusive shrub rose ranges where we can jointly plan volumes and timing.
