PERENNIAL BLUE™ – purple climbing rambler rose - Mehring
With its velvety mauve‑purple clusters and relaxed cottage‑garden charm, PERENNIAL BLUE™ brings colour, texture and rhythm to front and back gardens alike, clothing arches, fences and small house walls with airy, small semi‑double blooms. This ADR‑recognised rambler offers reliable flowering from early summer and then again in a generous second flush, giving you a long season of interest with relatively modest care. Own‑root growth supports long‑term stability, gradually forming a well‑balanced framework that settles securely even where stronger winds and rain call for dependable anchoring in the garden. Its climbing habit works beautifully in compact spaces, making vertical features out of pergolas and boundary structures without overwhelming a typical family plot. Over time you can expect the classic rose development arc – first the roots establish, then the framework extends, and by the third year the full ornamental display emerges as a coherent, flower‑laden structure. Medium disease resistance and straightforward seasonal care suit time‑pressed gardeners who still value thoughtful design around the home.

Usage options
Target area
Reasoning
Front‑garden arch or porch arbour
Compact, cluster‑flowered growth and moderate height make this rose ideal for framing a front path or porch without overshadowing windows or doors. Recurrent flowering keeps the entrance welcoming over a long season, even for beginners.
Clothing a fence in a family garden
The climbing habit and 2.4–3.8 m height allow it to soften standard garden fencing with a living curtain of mauve‑purple clusters, providing privacy and seasonal colour while remaining manageable with basic annual pruning for homeowners.
Small pergola beside a patio or seating area
Its medium vigour covers a modest pergola or sitting area without becoming unmanageable, while the semi‑double flowers and gentle fragrance lend a relaxed cottage feel that suits informal terraces used by families.
Training against a house wall or garage
Medium maintenance needs and own‑root resilience make it a dependable choice for vertical greening of walls, where it can be fan‑trained and renewed over time without complex techniques, reassuring busy gardeners.
Classic cottage‑style mixed border backdrop
The airy clusters and purple tones blend easily with perennials and traditional cottage favourites, adding height and colour without looking stiff, providing a soft, romantic backdrop prized by cottage‑garden enthusiasts.
Feature on an obelisk or tall support in a bed
Its moderate spread lets you spiral it around an obelisk or tripod, creating a vertical focal point in a small bed where space is tight but impact matters, a helpful solution for space‑conscious urbanites.
Family play‑garden boundary or screening strip
Used along boundaries, it offers seasonal screening and colour without forming a rigid hedge; own‑root growth allows gradual shaping and renewal, supporting long‑term, low‑fuss structure valued by practical planners.
Exposed, wind‑touched corner trellis
Once established on its support, the rambling framework and own‑root anchorage cope well where trellises catch the weather, providing a stable, flowered cover that suits those dealing with breezier plots and coastal‑influenced sites.
Styling ideas
Cottage Archway – Train over a slim metal or wooden arch, underplant with chives and dwarf French marigolds for a soft, edible‑ornamental mix – ideal for relaxed cottage‑style front‑garden owners.
Velvet Wall Veil – Fan‑train along wires on a sunny wall, pairing with pale foxgloves and white campanulas below to highlight the mauve‑purple clusters – suited to homeowners wanting elegant but simple structure.
Family Pergola – Let it ramble over a small seating pergola with fragrant herbs at the base, creating a dappled, flower‑strewn roof – perfect for families seeking a pretty, informal outdoor room.
Border Beacon – Spiral around a tall obelisk in a mixed border, surrounded by airy grasses and lilac perennials to echo its tones – good for beginners wanting a strong focal point without complex care.
Soft Screen – Weave through trellis panels along a boundary, interplant with cypress spurge ‘Fens Ruby’ for contrasting foliage – attractive to urban gardeners needing privacy and seasonal colour in limited space.

Awards and recognition
Holder of ADR certification in Germany (2013), Baden‑Baden Silver Medal (2006) and first prize at Baden bei Wien (2014), reflecting strong garden and show performance.
Growth and structural characteristics
Climbing rambler reaching about 240–380 cm high with a 150–260 cm spread; moderately dense, mid‑green, slightly glossy foliage and moderate prickliness; growth suited to arches, pergolas and walls.
Flower morphology
Semi‑double, cup‑shaped blooms with 13–25 petals, produced in large clusters of small flowers; remontant, with a notably abundant second flush prolonging display into later summer under normal garden care.
Colour data and phenology
Mid‑saturated crimson‑purple with silvery bloom and cool‑weather bluish tinge; buds dark magenta, fading towards greyish lilac in heat; colour richest in cooler spells, giving varied tones through the flowering period.
Fragrance and aroma
Fresh, lightly fruity character with very faint scent; fragrance is generally discreet in the garden, allowing flexible siting near seating areas or doors without overwhelming more strongly scented companions.
Hip characteristics
Forms small spherical red hips about 6–10 mm across in moderate quantities, extending visual interest into autumn and offering subtle wildlife value without creating heavy self‑seeding issues.
Resistance and winter hardiness
Rated to around −21 to −18 °C (H7, USDA 6b, Swedish zone 3); medium resistance to black spot, powdery mildew and rust, benefiting from good airflow and routine monitoring in humid or high‑pressure seasons.
Horticultural recommendations
Best on pergolas, arches, fences and walls with basic tie‑in and pruning; tolerates partial shade, prefers regular watering, and should be spaced 190–300 cm apart depending on use to allow full framework development.
PERENNIAL BLUE™ offers long-season purple clusters, manageable climbing growth and durable own-root vigour for arches, walls and pergolas, making it a thoughtful choice if you want a reliable, characterful rambler.
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.
