CLOS FLEURI BLANC – white bedding floribunda rose - Delbard
Step out after summer rain and this tall, upright rose lines your path with pure, snow‑white cups that stay clean and luminous in damp, changeable weather. Clos Fleuri Blanc builds a quietly confident presence: reliable repeat flowering, light, sweet fragrance and strong, modern disease resistance mean you can enjoy a refined, “girly” London front garden feel without complicated maintenance. As an own‑root shrub it forms a durable framework that bounces back from pruning and rough coastal winds, promising long‑term stability in small family plots and sustainable, rainwater‑fed gardens. Give it time to establish – roots in the first year, generous shoots in the second, full ornamental presence by the third – and this snow‑white floribunda becomes a lasting, low‑effort centrepiece.
Usage options
| Target area | Reasoning |
|---|
| London terraced-house front garden hedge |
The bushy, upright habit to around 130–170 cm creates a refined, semi-formal white hedge that frames steps and railings without overwhelming a narrow frontage, giving dependable structure for beginners. |
| Small rainwater-aware front garden bed |
Planted 60 cm apart in free-draining soil, the tall, narrow shrubs leave ground space for mulches and underplanting, suiting simple rainwater‑friendly designs where tidy, repeat white flowers offer long-season impact for busy owners. |
| Mixed white-and-lilac border with lavender or nepeta |
Its pure white clusters act as a calm backdrop to lavender, sage or nepeta, with light scent and neat, cup-shaped blooms adding elegance rather than clutter, ideal for cohesive, low‑effort planting schemes for style-conscious gardeners. |
| Informal flowering screen on a patio edge |
The combination of moderate spread and good height allows Clos Fleuri Blanc to blur boundaries between seating and garden, giving gentle privacy and long-flowering interest with minimal pruning for urban families. |
| Low-input bed on heavier clay or exposed sites |
Once soil is improved for drainage, the robust shrub and strong disease resistance stand up well to typical British wet spells and wind, supporting sustainable planting where resilience matters most for time-poor gardeners. |
| Statement specimen by a front door |
A single plant at 100 cm spacing develops into a tall, narrow column of shimmering white blooms and dark, glossy foliage, giving a welcoming focal point that stays elegant with light seasonal pruning for homeowners. |
| Own-root long-term family garden feature |
The own-root form builds a stable framework that can regenerate from the base after harder pruning, keeping its character for many seasons and retaining ornamental value without graft worries for long-term planners. |
| Large container on balcony or paved front terrace |
In a 40–50 litre pot with regular watering during dry spells, its upright habit and light fragrance bring vertical sparkle to small paved spaces, suiting those who garden mainly in containers for city dwellers. |
Styling ideas
- Front-row – Line a short London terrace path with Clos Fleuri Blanc and low lavender to create a soft, white-and-mauve welcome – ideal for busy homeowners wanting simple elegance.
- Rain-kissed – Combine with gravel, permeable paving and thyme along a drive, letting the tall white blooms rise from a free-draining, rainwater-friendly surface – perfect for sustainability-minded city gardeners.
- Snowglow – Plant three in a loose triangle with Nepeta and small alliums so the pure white cups float above a haze of blue – suited to beginners seeking reliable impact.
- Doorway – Place a single shrub beside a front step, underplanted with soft pink hardy geraniums, for a romantic, “girly” entrance – for those wanting charm with low maintenance.
- Balcony – Grow one plant in a 50 litre container with trailing ivy-leaved pelargoniums to spill over the edge, giving height, fragrance and colour on compact balconies – great for urban container gardeners.
Technical cultivar profile
| Property | Data |
|---|
| Name and registration |
Floribunda shrub from the Les Centenaires de Lourdes collection; registered as DELblan, marketed as Clos Fleuri Blanc, a white bedding floribunda rose for borders, hedges and specimen use. |
| Origin and breeding |
Bred by Georges Delbard in France in 1988, registered in 2010 and introduced after 2010 by Pépinières et Roseraies Georges Delbard and Georges Delbard SA for garden and landscape planting. |
| Growth and structural characteristics |
Bushy, upright shrub reaching about 130–170 cm high and 50–70 cm wide, with moderately thorny stems and dark green, glossy but relatively sparse foliage that shows off the clusters of white flowers. |
| Flower morphology |
Large, double, cup-shaped clusters with 26–39 petals per bloom; floribunda-type trusses provide generous first flowering and a similarly abundant repeat flush later in the season in suitable conditions. |
| Colour data and phenology |
Pale greenish-white buds open to pure, snow-white flowers, RHS 155C outer and 155D inner, remaining bright without yellowing, then slowly fading to pearly white with slightly creamy edges before petal drop. |
| Fragrance and aroma |
Lightly and delicately sweet fragrance typical of modern floribundas; scent is noticeable at close range on still days without overpowering, adding refinement to entrances and seating areas in family gardens. |
| Hip characteristics |
Sets only small, ellipsoid bright red hips around 5–7 mm when pollination occurs, as the double flowers limit fertility; hips add a discreet seasonal accent rather than a dominant autumn display. |
| Resistance and winter hardiness |
Good resistance to powdery mildew, black spot and rust; average heat and drought tolerance with watering needed in long dry spells; reliably hardy to about −23 to −21 °C, equivalent to RHS H7 and USDA 6a. |
| Horticultural recommendations |
Prefers a sunny position in well-prepared, free-draining soil; low maintenance with mainly formative and light renewal pruning, planted 50–100 cm apart depending on use, denser for hedges and looser for specimens. |
CLOS FLEURI BLANC offers tall, luminous white flowering, strong disease resistance and long-lived own-root durability, making it a thoughtful choice for relaxed, sustainable family gardens and compact urban spaces alike.
