HYBRIDA – white rambler climbing rose – pharmaROSA® NEONATAL
Vertical production with HYBRIDA as tray-grown own-root material gives you a stable base for trained climber lines, combining medium-maintenance management with reliable, once-a-season flowering for pergola, wall and park work. As a premium bronze-rated rambler in the climbing rose collection, it supports exclusive, space-defining ranges where a clear architectural habit matters and 5–7 L trained-finish formats are preferred. The good self-cleaning clusters reduce labour at flowering peak, while the heat- and frost-tolerant framework suits UK nursery networks that must perform consistently in cooler, wind-exposed regions, providing confidence for multi-site distribution and project fulfilment. Own-root propagation underpins long-term renewable stock stands for cultivar maintenance and vertical garden collections, with Year 1 focused on roots, Year 2 on structural shoots, and Year 3 delivering full ornamental impact.
