MEICOLOSS – red park rose – Meilland (pharmaROSA® NEONATAL)
MEICOLOSS Meidiland® offers a vigorous, bushy framework ideal for nursery beds and park-oriented ranges where reliable structural coverage is required over larger areas. As own-root pharmaROSA® NEONATAL material, these tray-grown cuttings provide a stable, renewable base for scalable production, supporting uniform 2–3 L standard container lines for retail and reseller programmes. The dense, glossy dark-green foliage sets a strong background to the rich, deep red, semi-double clusters, giving a consistent visual effect in flowerbeds, hedging and urban green schemes. Heat- and drought-tolerant performance supports planning for exposed or resource-conscious projects, complementing UK schemes where reliable structure under varied weather is expected. Own-root stock underpins long-term regeneration and predictable performance for multi-year production cycles, with roots consolidating in year one, framework build in year two and full ornamental value typically from year three, allowing You to plan capacity and timing with confidence. This combination of vigour, red mass-effect flowering and robust shrub habit supports thematic rose gardens, collection plantings and public-realm contracts.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Registered as MEIcoloss with current trade naming MEICOLOSS Meidiland®, classified as a shrub-type park rose for mass planting and structural use in professional ranges. |
| Origin and breeding |
Bred by Alain Meilland, Meilland International SA, France, around 2000, introduced in 2001 via Meilland Richardier; parentage is undocumented but aligned with vigorous Meidiland® shrub lines. |
| Growth and structural characteristics |
Bushy, spreading shrub reaching about 120–170 cm in height and 130–190 cm spread, with very dense, dark-green glossy foliage and moderate prickliness, forming substantial, coverage-oriented plants. |
| Flower morphology |
Semi-double, cupped clusters carrying roughly 13–25 petals, medium-sized blooms around 1.5–2.75 inches, flowering in remontant flushes with abundant second flowering supporting extended display. |
| Colour data and phenology |
Rich deep-red colour without orange or purple tones; buds dark velvety red, opening to vivid deep-red outer petals with slightly lighter inner petals, darkening toward burgundy while remaining intense through flowering. |
| Fragrance and aroma |
No noticeable fragrance; classed as an unscented rose, with semi-double flowers offering only moderate pollinator attraction due to partially concealed stamens limiting accessibility. |
| Hip characteristics |
Occasional small hips may form, typically spherical up to about 8 mm diameter, with limited ornamental value and no specific colour or shape data recorded. |
| Resistance and winter hardiness |
Hardy to approximately −26 to −23 °C (H7, USDA 5b, Swedish zone 4); disease resistance is low, very susceptible to powdery mildew and black spot, moderate against rust, with good tolerance to heat and drier conditions. |
| Horticultural recommendations |
Recommended for flowerbeds, edging, hedges, parks, urban green spaces and occasional cutting; supplied as bush-trained compact plants for standard container production, but requires regular plant protection due to disease sensitivity. |
