Gärtnerfreude ® RigoRosen® KORstesgli – pharmaROSA® NEONATAL rooted cutting
Groundcover production with Gärtnerfreude® gives You a uniform, spreading base cultivar for mass-planting projects where fast surface closure and low ongoing care are critical. As a tray-grown pharmaROSA® NEONATAL own-root cutting, it integrates smoothly into nursery propagation beds and 1.5–2 L container programmes, building wholesale stock that matures reliably from roots in year one to framework in year two and full ornamental value by year three. Its dense glossy foliage, remontant flowering and consistently raspberry-red colour support project ranges aimed at landscape contractors and public-realm schemes, especially where long-season visual stability and low cleaning inputs are valued. Good disease resistance and H7 winter hardiness offer dependable performance for UK nursery networks, including harsher northern sites where robust winter and wind tolerance is an asset, while own-root longevity and quick canopy closure help You maintain homogeneous blocks, predictable capacity and low replacement in large-scale, project-driven production.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Groundcover shrub rose from the RigoRosen® collection; registered as KORstesgli with current trade name Gärtnerfreude ® RigoRosen® KORstesgli and ARS exhibition name Gärtnerfreude®. |
| Origin and breeding |
Bred by Wilhelm Kordes III. in Germany (breeding year 1991) from ‘The Fairy’ × [(‘The Fairy’ × unknown seedling) × ‘Amanda’], introduced by W. Kordes’ Söhne in 1999, registered 1998. |
| Awards and recognition |
ADR trial award (2001); Baden‑Baden Gold Medal (1999); Kortrijk Gold (2001) and Silver (1999); Gold Standard Award UK (2008); Gerald Maylen Award for best groundcover in Australia. |
| Growth and structural characteristics |
Low, spreading habit 40–65 cm high and 50–90 cm wide, forming dense, glossy dark green foliage with moderate prickles; good self-cleaning as most spent blooms drop naturally, limiting grooming work. |
| Flower morphology |
Very double, small spherical pompon blooms (0.5–1.5 in) borne in clusters; petal count above 40 with remontant flowering, producing an abundant second flush that maintains a carpet effect in plantings. |
| Colour data and phenology |
Bright raspberry-red flowers (RHS 53A outer, 53B inner) with glossy newly opened blooms; colour hardly fades even in strong sun, shifting slightly to rose-pink while retaining a uniform decorative appearance. |
| Fragrance and aroma |
Fragrance is very weak and barely perceptible; primarily selected as an ornamental groundcover for visual performance rather than scent, with highly double blooms that emphasise colour mass and coverage. |
| Hip characteristics |
Hip set is generally poor due to very double blooms; where present, produces small spherical red hips 4–7 mm in diameter, not a key ornamental or production feature in typical landscape uses. |
| Resistance and winter hardiness |
Rated resistant to powdery mildew, black spot and rust; hardy to about −26 to −23 °C (RHS H7, Swedish zone 4, USDA 5b), supporting reliable outdoor production and landscape performance in cold regions. |
| Horticultural recommendations |
Suited to groundcover, beds, slopes, parks, containers and urban green spaces; low maintenance with minimal upkeep, ideal as a uniform, dense, bush-trained finished product for project mass planting routes. |
