MEICOLOSS – red park rose – Meidiland®

This vigorously growing shrub rose creates a colossal presence in family gardens, building a broad, bushy framework that is easy to shape into hedges, borders or a single statement plant. Its dense, dark green foliage gives a constantly green backdrop, while clusters of radiant, deep-red blooms appear in generous flushes from early summer, with a second flowering that is pleasantly reliable. Once established, the plant shows hardy resilience to winter cold and copes well with summer heat and drier spells, an advantage in exposed or breezy plots where good airflow helps offset higher humidity and disease pressure typical of British gardens. As an own-root shrub, it forms a balanced structure over time, regenerating naturally from the base for a long-lived, tidy presence in beds and along paths. In the first year it concentrates on roots, the second year brings stronger shoots, and by the third season it typically reaches full ornamental value in both spread and flowering. With its unscented, semi-double flowers and glossy foliage, this rose lends a quietly elegant formality to classic front gardens and more relaxed cottage-style mixes alike.



Usage options

Target areaReasoning
Front garden focal shrub The strong, upright-to-arching growth builds a substantial shrub that quickly fills its allotted space, giving a clearly defined focal point visible from the house and street, reassuring those who want impact without intricate design skills; well suited to the needs of the beginner.
Loose flowering hedge Planted at the recommended spacing, the dense, dark foliage and spreading habit create a broad, leafy screen that remains visually effective even when not in flower, ideal for softening boundaries in family gardens and providing structure for the homeowner.
Small park-style bed at home The remontant, cluster-flowering habit offers waves of vivid red colour through summer, echoing public park plantings but on a domestic scale, giving a sense of order and continuity that appeals to the aesthetically focused gardener.
Low-maintenance structural backdrop With good frost hardiness and tolerance of heat and drier spells, the shrub forms a dependable green backdrop behind perennials and grasses, reducing the need for frequent replanting and supporting a long-term layout for the busy urbanite.
Cottage-style mixed border The bushy, spreading habit and rich red blooms combine well with herbaceous companions, allowing informal underplanting while the rose provides height and volume, suiting those who like relaxed planting but straightforward care as a time-pressed enthusiast.
Specimen in large planter In a 40–50 litre or larger container, its vigorous growth can be channelled into a single, shapely shrub for patios or paved front gardens, bringing height and colour where soil is limited, a practical solution for the space-conscious town-dweller.
Perimeter planting in windy sites The solid framework and good rooting make it suitable for more exposed spots, where its spreading habit helps anchor the planting and cope with brisk coastal or open-site breezes that often challenge the average householder.
Family-friendly edging to lawns Regular pruning after establishment keeps the shrub within bounds, while its glossy foliage and showy clusters provide a clear visual edge to paths and lawns, helping shape a tidy, comprehensible garden layout for the practical family.

Styling ideas

  • Park-edge elegance – Use as a loose hedge along the front boundary, paired with low evergreen shrubs for year-round structure – ideal for homeowners wanting a smart, traditional feel.
  • Cottage sweep – Curve a line of shrubs behind drifts of lupins and tall verbena to blend formality with relaxed colour – suited to lovers of classic cottage borders.
  • Red accent island – Create a small central bed in lawn with three shrubs in a triangle, underplanted with low grasses – for those seeking a simple yet striking focal point.
  • Patio sentinel – Grow a single plant in a generous 50-litre container flanking the front door, combining it with trailing seasonal bedding – perfect for small-plot or paved-front gardeners.
  • Family framework – Place shrubs at the corners of a play lawn to anchor the space, leaving clear sightlines and easy mowing strips – designed for busy families wanting order with minimal fuss.

Technical cultivar profile
PropertyData
Name and registration Meicoloss Meidiland® MEIcoloss; registered shrub/park rose, exhibition category park rose for mass plantings, with the cultivar name reflecting its vigorous, large-growing shrub character.
Origin and breeding Bred by Alain Meilland, Meilland International SA, France; bred around 2000 and introduced in 2001 via Meilland Richardier, with parentage not publicly recorded for this cultivar.
Growth and structural characteristics Bushy, spreading shrub 120–170 cm tall and 130–190 cm wide, with dense, glossy dark green foliage and moderate prickliness; forms a broad, substantial framework suitable for hedging and specimen use.
Flower morphology Semi-double, cupped, cluster-flowering blooms of medium size, typically 13–25 petals; remontant with abundant first and second flushes, providing repeated colour across the main flowering season.
Colour data and phenology Rich deep red flowers (RHS 46A outer, 46B inner) with a glossy surface, darkening slightly to burgundy-red as they age; colour remains vivid without orange or purplish tones, maintaining strong visual impact.
Fragrance and aroma No noticeable fragrance; bred primarily for colour effect and landscape presence rather than scent, making it suitable where visual structure and flower display are the main design priorities.
Hip characteristics Occasionally forms small round hips up to 8 mm in diameter, generally sparse and not a major ornamental feature, so deadheading may be guided mainly by desired appearance and flowering management.
Resistance and winter hardiness Hardy to approximately –26 to –23 °C (RHS H7, USDA 5b, Swedish Zon 4); tolerates heat and drier periods well but is very susceptible to powdery mildew and black spot, so regular plant protection is advisable.
Horticultural recommendations Best in well-prepared soil with good drainage and full sun to partial shade; allow ample spacing as a specimen or hedge, and plan consistent watering, feeding and disease control for reliable long-term performance.

MEICOLOSS offers vigorous structure, vivid red flowering and reliable cold tolerance as an own-root shrub that matures into a stable, long-lived feature; consider it where you want lasting form with straightforward care expectations.

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.
