Delrosar Intense Fragrances DELrosar – pharmaROSA® NEONATAL own-root climber
As a Large-Flowered Climber from the Intense Fragrances collection, Delrosar offers a fragrant and visually vertical solution for professional own-root production aimed at trained climber lines for arbours, pergolas, arches, fences and walls. Its rambling habit, dense dark green foliage and large, very full, clustered blooms create a feature product route, well aligned with exclusive, space-defining specialty ranges for retail and reseller partners. The pale-pink, white-striped flowers with medium-strength scent repeat well, supporting premium presentation in 5–7 L trained climber formats, while own-root material supports long-term sustainability through stable vigour, regeneration and predictable stands under UK nursery conditions that often demand reliable winter and wind tolerance in exposed projects. Homogeneous, tray-rooted cuttings at 3–6 months make scheduling and storage manageable for nurseries planning trained-staked canes, with year one focussed on roots, year two on structural shoots and year three on full ornamental impact in finished stock. This combination of repeat flowering, colour stability and medium maintenance level provides confidence for integrators and wholesale networks building distinctive vertical collections on a robust own-root platform.
