WILLIAM LOBB – deep purple historic moss rose - Laffay
If you love romantic, historic roses but prefer easy decisions in the garden, William Lobb offers a richly scented step back in time that still works for today’s Irish cottage borders and compact city plots. This tall, upright moss rose carries large, double, crimson-purple rosettes that fade beautifully to a smoky, old-fashioned lilac, filling the air with a strong, long-lasting perfume during its main summer flush. Once established in free-draining soil, it copes steadily with our cool summers and frequent showers, handling coastal breezes and humid conditions with reassuring poise. Grown on its own roots in a handy 2-litre pot, it settles in reliably and builds a framework that can flower for decades with thoughtful seasonal care, rewarding patient gardeners as roots strengthen, then shoots extend, and finally full ornamental value develops over the first three years. Ideal where you want a single, characterful shrub to anchor a planting, this rose suits those who appreciate atmosphere, fragrance and character more than constant fuss, letting you enjoy gentle contentment on short walks through the garden whenever it is in bloom.
Usage options
| Target area |
Reasoning |
| Feature shrub in a small to medium family garden |
William Lobb’s tall, upright habit and broad spread give you a ready-made focal point, ideal for anchoring a cottage-style bed or softening a boundary in an average Irish family garden where one strong specimen can do a lot of visual work for fragrance-loving homeowners. |
| Heritage-style Irish cottage border |
The once-flowering but season-spanning display of large, rosette blooms in shifting purple and lilac tones creates a traditional, storybook mood that pairs naturally with perennials, perfect for gardeners seeking an old-world feel without needing complex design experience. |
| Dublin terraced-house front garden |
This rose’s vertical structure and modest footprint at ground level suit narrow beds beside paths or railings; one shrub can frame a doorway with scent and colour, offering maximum impact from limited space for busy urban residents who still want a touch of romance. |
| Lightly shaded side garden or north-east aspect |
Its tolerance of partial shade lets you use trickier side beds that miss full midday sun; morning or dappled light is usually enough for a good flowering show, adding perfume and atmosphere where many roses struggle for hobby gardeners working with awkward sites. |
| Large container on patio or gravel area |
Planted in a deep, free-draining pot of at least 40–50 litres, this own-root shrub can be grown as a movable feature, allowing you to enjoy historic flowers and scent near seating while keeping roots above heavy clay, suiting renters or flexible-minded garden planners. |
| Character hedge or informal boundary line |
Spacing plants along a line at around 110 cm gives a loose, romantic hedge with richly coloured, perfumed blooms and mossy buds; it is best for gardeners happy to deadhead and prune annually who value atmosphere and privacy more than strict formality. |
| Climate-conscious traditional planting in exposed locations |
Once established in well-drained soil, William Lobb forms a resilient woody framework that copes steadily with frequent rain and brisk Atlantic-tinged winds, keeping its shape and presence for many seasons, reassuring environmentally aware gardeners planning long-lived plantings. |
| Collectors’ historic rose corner |
As an 1855 moss rose with Royal Horticultural Society Award of Garden Merit, this shrub offers genuine heritage interest and strong, old-fashioned perfume, rewarding patient rose enthusiasts who enjoy caring for characterful, long-lived plants in a dedicated area of the garden. |

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
William Lobb is a historic moss rose, trade name William Lobb – Heritage rose – Laffay; unregistered cultivar, classified within the Rós stairiúil commercial group and moss rose exhibition class. |
| Origin and breeding |
Bred by Jean Laffay in France and introduced in 1855, this moss rose is a seedling descendant of ‘Gloire des Mousseux’, distributed originally by Laffay and valued as a classic nineteenth-century shrub. |
| Awards and recognition |
Holds the Royal Horticultural Society Award of Garden Merit, granted in 1993, recognising its enduring garden performance, ornamental value and reliability under typical temperate-climate garden conditions. |
| Growth and structural characteristics |
Forms an upright to slightly arching shrub 150–230 cm tall and 100–160 cm wide, with moderately dense, dark green foliage, densely thorned mossy stems and a strong presence suited to specimen or hedge use. |
| Flower morphology |
Large, double, rosette-shaped blooms with 26–39 petals, typically 7–10 cm across, borne in clusters; once-flowering in early summer, with weak self-cleaning so spent blooms usually benefit from regular deadheading. |
| Colour data and phenology |
Flowers open deep crimson-purple (RHS 60B–61B tones), then mellow through smoky greyish-lilac to silvery-centred shades; colour lightens more quickly in strong sun but overall effect remains richly moody and romantic. |
| Fragrance and aroma |
Noted for a strong, full-bodied old-rose perfume that lingers well in still air; the scent is rich and enveloping, enhancing seating areas or paths where the once-yearly flowering can be fully appreciated. |
| Hip characteristics |
Occasionally forms ovoid rose hips 14–22 mm in diameter, in red-orange RHS 40A shades; hips are generally sparse on well-deadheaded plants but can add autumn interest when some spent blooms are left. |
| Resistance and winter hardiness |
Hardy to around −32 to −29 °C (USDA 4b, RHS H7, Swedish Zone 5) but has medium susceptibility to powdery mildew and black spot and is very prone to rust, needing regular preventive care in damp climates. |
| Horticultural recommendations |
Best in fertile, well-drained soil; avoid waterlogging on heavy clay with raised beds or grit. Plant with 120 cm spacing in beds or 110 cm for hedges, and provide consistent pruning, deadheading and disease monitoring. |
WILLIAM LOBB offers richly scented, once-a-year deep purple blooms, strong structural presence and long-term character, while its own-root form supports a durable framework for gardeners seeking a dependable, atmospheric shrub to enjoy over many seasons.
