PERENNIAL BLUE™ – purple climbing rambler rose - Mehring
If You dream of a romantic cottage-style entrance or a softly flowering boundary without complicated gardening, PERENNIAL BLUE™ is a graceful climbing rambler that rewards simple care with months of colour. Its clusters of small, cup-shaped blooms shift through velvety lavender and mauve purple tones, creating an airy, nostalgic veil of flowers along arches, walls and fences even where summers are cool and damp and soil can be heavy and clay-leaning. Remontant flowering means it returns with an abundant second flush for a long season of gentle display, while its own-root nature supports a long-lived, regenerating structure that settles steadily into Your garden over the years. In Year 1 it focuses on roots, in Year 2 on new shoots, and by Year 3 You enjoy its full ornamental value. Medium maintenance and reliable hardiness make it a reassuring choice for beginners, yet its award-winning pedigree also delights experienced collectors.
Perennial Blue™ with a very faint, fresh fruity fragrance.
Perennial Blue™ with spherical red rose hips on the stem
Use cases
Target area
Reason
Front-garden arch or pergola near the entrance
The climbing, long-caned habit easily covers arches and pergolas, giving Your entrance a welcoming tunnel of mauve-purple clusters without needing elaborate pruning, ideal if You simply want to guide the canes and enjoy the effect as a beginner
Family garden fence or boundary screen
Its 240–380 cm height and 150–260 cm spread create a soft, flowery screen along fences, helping to divide space and provide privacy while still letting light through for a friendly, non-oppressive boundary appreciated by the whole family
Cottage-style wall planting in rural gardens
Trained against a sunny or lightly shaded wall, the continuous mauve‑purple clusters and small red hips echo traditional cottage gardens, pairing well with herbs and perennials for a romantic, slightly informal look loved by cottage‑garden enthusiasts
Urban front garden with limited ground space
Because it grows up rather than out, this rambler suits narrow beds in town gardens, bringing vertical colour where planting depth is tight, giving busy urban homeowners a strong impact without needing a large plot
Coastal or exposed Irish site on a sturdy support
Good hardiness and the ability to cope with cool, humid conditions make it suitable for many Irish coastal and wind‑influenced gardens when given a solid support, reassuring gardeners in breezier areas seeking reliable structure
Partially shaded side path or north–east aspect
Its tolerance of partial shade allows flowering along side paths and less sunny aspects, brightening spaces where many roses struggle, ideal for homeowners wanting colour beyond the main sunny terrace area
Large container on patio, balcony or terrace
When planted in a minimum 40–50 litre container with a trellis, it brings vertical colour to patios or balconies; regular watering and feeding keep it flowering well, suiting those who garden mainly in pots and outdoor rooms
Long-term feature rose for future garden structure
As an own‑root climber it matures steadily, building lasting framework branches that recover better from winter damage, giving You a dependable, evolving focal point that becomes more impressive each year for long‑range garden planners
Decorating ideas
Cottage Archway – Train PERENNIAL BLUE™ over a metal arch with lavender and catmint at the base for a soft, country look – for romantically inclined front‑garden owners
Shimmering Fence – Combine along a fence with dwarf French marigolds and chives to echo its mauve blooms with cheerful underplanting – for busy families who like low-fuss colour
Patio Feature Pot – Grow it in a 40–50 litre tub with a fan trellis, underplanted with trailing thyme for scent and texture – for balcony and terrace gardeners
Rural Wall Veil – Let it curtain a south-facing stone wall, softened with cypress spurge ‘Fens Ruby’ and hardy geraniums – for rural cottage and farmhouse settings
Evening Walkway – Line a garden path with two or three plants on obelisks, where their silvery-toned petals glow in low light – for those who enjoy evening strolls in the garden
Technical cultivar profile
Property
Data
Name and registration
Rambler and large flowered climber rose, registered as Mehv9601, traded as PERENNIAL BLUE™. Belongs to the climbing rose commercial group; ARS exhibition name Perennial Blue, verified cultivar authenticity.
Origin and breeding
Bred by Bernard F. Mehring in the United Kingdom from Super Excelsa × Veilchenblau. Introduced in 2003, with initial distribution by Eurosa in Germany; registration year data are not available.
Awards and recognitions
Holds ADR status in Germany (2013), reflecting proven garden performance. Awarded Baden‑Baden Silver Medal in 2006 and first prize at Baden bei Wien in 2014, confirming strong ornamental merit.
Growth and structure
Vigorous climbing growth with canes reaching about 240–380 cm in height and 150–260 cm spread. Foliage is moderately dense, mid‑green and slightly glossy, with moderate prickliness requiring gloves when training or pruning.
Flower morphology
Semi‑double, cup‑shaped blooms with 13–25 petals, produced in large, showy clusters. Small individual flowers, approximately 0.5–1.5 inches, give an elegant, finely textured appearance when the plant is fully in bloom.
Colour and phenology
Mid-saturated crimson‑purple base with silvery, bluish tones in cooler weather. Buds open vivid mauve‑purple, then soften to greyish lilac with silvery edges; colour may fade in strong sun. Remontant, with a notably abundant second flush.
Fragrance and aroma
Fragrance is very faint, with only a light fresh, fruity impression close to the blooms. Semi‑double flowers offer partial pollinator friendliness, as some stamens remain accessible, attracting insects moderately in good weather.
Rose hip characteristics
Produces moderate quantities of small, spherical red hips, about 6–10 mm in diameter. Hips extend seasonal interest into autumn and may attract birds, though berry production can vary with pruning and flowering success.
Resistance and hardiness
Hardy to approximately −21 to −18 °C (H7; USDA zone 6b; Swedish zone 3). Disease resistance is medium to powdery mildew, black spot and rust; benefits from good air flow and timely preventive care in humid seasons.
Horticultural recommendations
Best on pergolas, arches, fences or walls with sturdy support. Plant with 190–300 cm spacing depending on use; about 0.3 plants/m² for mass planting. Prefers moderate watering, with regular feeding to sustain repeat flowering.
PERENNIAL BLUE™ offers romantic purple clusters, reliable repeat flowering and long-lived own-root growth that settles into arches, walls or large containers; a thoughtful choice if You would like a graceful, enduring climber.
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”, but makes the essence of pharmaROSA® own-root production tangible: how the plant is built, what the root system is like and how the shoots renew themselves. The footage was therefore taken at different times, showing plants at different stages of development, so mixed leaf coverage or differing growth stages may appear in the videos. This is not a “sample” of the batch delivered, but an illustration of how the technology works. The current condition of the rose available to order — typical of the given period and similar to what you can expect to receive in the parcel — is shown at the top of the product page.
