PERENNIAL BLUE™ – purple climbing rambler rose - Mehring
Bring a touch of storybook romance to your garden with PERENNIAL BLUE™, a long-lived own-root rambler that clothes arches, fences and pergolas in clouds of violet-purple bloom. Its generous clusters of small, semi-double flowers create a soft cottage feel from early summer, with a strong repeat later in the season to keep your garden looking full and colourful. This versatile climber is well suited to typical UK gardens, coping reliably even where breezes and rain are regular visitors along more coastal sites. Once planted, the own-root form develops steadily, settling in with a firm root system and dependable top growth that supports a graceful, medium-thorny framework for many years. Over time it matures into a stable feature with lasting ornamental value, needing only straightforward annual tidying rather than complex pruning. The 2-litre potted plant is easy to handle, plantable throughout the season, and quickly becomes part of your everyday garden view, softening structures and creating a sense of lived-in cottage charm.

Usage options
Target area
Reasoning
Pergola over a seating area
Ideal for covering a pergola where you would like dappled shade and a romantic atmosphere, its rambling habit and repeat flowering create a long-season floral canopy that frames afternoon tea or evening relaxation for garden-lovers.
Garden arch at an entrance
Trains neatly over a metal or wooden arch, giving a welcoming tunnel of purple clusters; medium vigour allows you to maintain a clear passage, while its long lifespan means the entrance stays established and inviting for home-owners.
Fence or boundary screen
Works beautifully along a family-garden fence, clothing it with foliage and colour without becoming unmanageable; moderate height and spread provide privacy and softness, supporting a traditional cottage look for busy-families.
Wall or house-side trellis
Climbs readily on trellis fixed to a sunny wall, with own-root resilience giving stable growth against structures and coping well where wind-driven rain is a regular part of the local weather for coastal-gardeners.
Informal cottage-garden backdrop
Makes a natural-looking backdrop behind herbaceous borders and kitchen-garden beds; the mauve-purple clusters complement soft pinks, whites and silver foliage, enhancing an English cottage style without demanding high-maintenance routines for cottage-enthusiasts.
Family play-garden divider
Used on a simple post-and-wire frame, it can gently divide play areas from vegetable or flower beds; its structured yet not overly vigorous habit allows easy pruning to keep spaces safe and practical for young-families.
Seasonal feature by patio or terrace
Positioned to rise behind a seating terrace, it provides changing interest from fresh buds to coloured hips; modest fragrance keeps it understated near doors and windows while the colour adds character through the season for patio-owners.
Own-root collector’s specimen climber
Well suited to gardeners who appreciate long-lived, own-root climbers that can regenerate from the base if cut back hard, building up a reliable structure and ornamental display over successive seasons for rose-collectors.
Styling ideas
Cottage Archway – Train PERENNIAL BLUE™ over a simple timber arch, underplant with chives and dwarf French marigolds for kitchen-garden charm – for lovers of traditional cottage entrances.
Romantic Pergola – Let it drape from a pergola above a seating area, pairing with scented climbers in softer hues for a layered, storybook canopy – for afternoon-tea hosts.
Kitchen-Garden Screen – Use along a wire fence at the edge of veg beds, backed by cypress spurge for contrasting foliage texture – for practical gardeners who like pretty boundaries.
Pastel Backdrop – Combine with pale pink shrub roses and silvery perennials to create a harmonious, painterly background behind a lawn – for homeowners seeking a gentle, romantic palette.
Family Corner – Grow on a trellis to soften a shed or play-corner, with planting kept high and regularly pruned to accommodate everyday use – for families wanting safe, soft-focus screening.
Technical cultivar profile
Property
Data
Name and registration
Rambler and large-flowered climbing rose; registered as Mehv9601, marketed as PERENNIAL BLUE™ and Perennial, suitable for exhibition as a climber or rambler rose.
Origin and breeding
Bred by Bernard F. Mehring in the United Kingdom from Super Excelsa × Veilchenblau; introduced by Eurosa in Germany in 2003 for garden and exhibition use.
Awards and recognition
Holder of the ADR German quality mark since 2013, plus Baden-Baden Silver Medal 2006 and first prize at Baden bei Wien in 2014 for garden and show performance.
Growth and structural characteristics
Climbing habit with 240–380 cm height and 150–260 cm spread; moderately thorny canes and mid-green, slightly glossy foliage of medium density forming an elegant, arching framework.
Flower morphology
Small, cup-shaped, semi-double blooms with 13–25 petals, borne in large clusters; remontant, with a strong second flush that maintains decorative coverage through much of the summer.
Colour data and phenology
Mid-saturated crimson-purple blooms (RHS 77A outer, 77B inner) with silvery bloom; colour is most intense in cool weather and may fade towards greyish-lilac with a soft silvery edge in strong sun.
Fragrance and aroma
Very light, almost imperceptible fragrance with a fresh, faintly fruity character; semi-double flowers provide moderate pollinator interest where stamens remain partially visible.
Hip characteristics
Produces small, spherical red hips 6–10 mm across in moderate quantities, adding discrete autumn interest without overwhelming the overall habit or requiring special management.
Resistance and winter hardiness
Hardy to approximately –21 to –18 °C (RHS H7, Swedish zone 3, USDA 6b); medium resistance to powdery mildew, black spot and rust, benefiting from basic preventative care in humid sites.
Horticultural recommendations
Best on pergolas, arches, fences and walls; plant at 190–300 cm spacing, provide moderate watering, and allow room for training to show clusters fully and simplify seasonal pruning tasks.
PERENNIAL BLUE™ offers richly coloured cluster flowering, versatile climbing for arches or pergolas, and durable own-root growth that matures into a long-lived feature, making it a thoughtful choice for relaxed, romantic gardens.
Pollinator Attraction:
Semi-double, 13–25-petalled flowers moderately attract pollinators because the semi-double bloom form can partially obscure the stamens, reducing the accessibility of pollen and nectar.
Pollinator-Friendly Rating:
Due to its semi-double flowers, it is considered partially pollinator-friendly.

Information about the videos
The video series is not a “seasonal showcase”; it illustrates the essence of pharmaROSA® own-root cultivation in a tangible way: how the plant is built up, what the root system is like and how the shoot system regenerates. The recordings were therefore made at different times and with plants at various stages of development, so mixed foliage levels and differing stages of growth may appear in the videos. They are not a ‘sample’ of the batch dispatched, but a visual explanation of how the technology works. The current condition of the rose available to order — typical for the given period and similar to what you can expect to receive in the parcel — is shown in the upper part of the product page.
