Dioressence® Grands Parfums DELdiore – pharmaROSA® NEONATAL rooted cutting
Fragrance is the defining asset of Dioressence® DELdiore, a Grands Parfums floribunda selected here as professional own-root propagation material for nursery and wholesale bedding production routes. As a bush-trained, compact growth type with upright, moderately dense foliage, it adapts smoothly to standard-container workflows, particularly 2–3 L programmes feeding into retail and reseller channels. Its large, double, cluster-flowered heads deliver a distinctive purple colour range, with good retention and attractive tonal shifts that support reliable garden performance as a standard finished product line. On own roots, stands remain stable and regenerative over time, supporting predictable capacity, low replacement rates and long-term stock blocks. With medium maintenance needs and average disease resistance, production planning is straightforward, and occasional plant protection can be scheduled into routine programmes. The very strong, long-lasting classic rose scent connects well with UK thematic rose gardens and collection-led projects, while the H7 hardiness rating supports supply into cooler regions where winter and wind conditions are demanding. Under typical nursery timelines, root establishment in year one, structural shoot build in year two and full ornamental impact by year three allow you to phase outputs across seasons and keep consistent quality through your network.
