Clos Fleuri Blanc Les Centenaires de Lourdes® DELblan – pharmaROSA® NEONATAL rooted cutting
Clos Fleuri Blanc Les Centenaires de Lourdes® DELblan offers professional growers a compact, bush-trained floribunda base that is well suited to standard container production, delivering predictable, remontant white clusters for retail-ready bedding ranges. Its bushy upright habit and 130–170 cm height give a versatile shrub structure for 2–3 L lines and larger 40–50 litre specimens where a reliable, snow-white garden performer is required. The cultivar’s disease resistance profile (powdery mildew, black spot and rust) and low maintenance requirement support homogeneous blocks and low replacement in nursery beds, useful for networks serving public and institutional projects in cooler regions where good winter and wind tolerance is crucial. As an own-root NEONATAL cutting, it builds a long-lived, stable production base: roots establish in the first year, shoots structure in the second, and full ornamental value stabilises from the third season onwards. The dazzling, non-yellowing white flowers and light fragrance add clear retail appeal, while dark green, glossy foliage on moderately thorny canes underpins durable garden performance for thematic collections and show plantings. Tray-grown NEONATAL material integrates efficiently into nursery workflows, giving scalable, predictable output volumes and dependable identity for collection and wholesale ranges.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Floribunda shrub marketed as Clos Fleuri Blanc Les Centenaires de Lourdes DELblan; registered as DELblan in 2010, with verified authenticity for professional own-root NEONATAL propagation and premium bronze quality grading. |
| Origin and breeding |
Bred by Georges Delbard in France in 1988, later introduced after 2010 through Pépinières et Roseraies Georges Delbard and Georges Delbard SA, offering a modern floribunda type with stable characteristics for commercial production. |
| Growth and structural characteristics |
Bushy, upright shrub, 130–170 cm high with 50–70 cm spread, moderately thorny shoots and sparse but dark green, glossy foliage, forming compact, bush-trained plants suitable for standard containers and structured bedding layouts. |
| Flower morphology |
Double, 26–39 petalled cup-shaped blooms of large size on cluster-flowered inflorescences, remontant with a similarly abundant second flush, providing sustained ornamental value for bedding and shrub applications through the main season. |
| Colour data and phenology |
Flowers open from pale greenish buds to a pure, dazzling snow-white that does not yellow, then fade to pearly white with creamy edges; RHS 155C/155D tones and uniform discs support consistent colour presentation in production blocks. |
| Fragrance and aroma |
Light, delicately sweet fragrance that adds a subtle sensory layer without dominating mixed plantings, suitable for high-density plantings and retail environments where a gentle scent is preferred over intensely perfumed cultivars. |
| Hip characteristics |
Due to its fully double blooms it sets only small ellipsoid hips, about 5–7 mm in diameter, bright red in colour, with modest visual impact, so hip display is secondary to the long-season value of the white flowers. |
| Resistance and winter hardiness |
Good resistance to powdery mildew, black spot and rust, combined with hardiness rated to approximately -23 to -21 °C (RHS H7, USDA 6a, Swedish Zone 3), supporting reliable overwintering and reduced loss in exposed or cool sites. |
| Horticultural recommendations |
Best suited to standard container production as a bush-trained compact shrub in 2–3 L pots or larger feature containers; low maintenance, average heat and drought tolerance with irrigation required in prolonged dry spells, no specific primary use data. |
Clos Fleuri Blanc Les Centenaires de Lourdes® DELblan offers disease resistance, reliable white floribunda performance and scalable own-root predictability, making it a practical option for stable nursery programmes where we can align capacities and scheduling together.
