Noasun Décorosiers® NOAson – pharmaROSA® NEONATAL rooted cutting
With its groundcover habit, remontant flowering and uniformity, Noasun Décorosiers® NOAson offers a reliable, low-input option for mass project plantings where fast coverage and predictable structure are critical. This pharmaROSA® NEONATAL own-root material delivers stability for nursery propagation beds and 1.5–2 L container grow-on, supporting dense, bush-trained, landscape-focussed finished stock. Its ADR-level resistance, glossy dark-green foliage and soft yellow, self-cleaning flowers help maintain clean presentation with minimal maintenance in parks, urban schemes and contractor portfolios, while good heat and drought tolerance suits exposed UK sites, including cooler regions where winter and wind tolerance supports dependable public-realm performance. As with other own-root lines, you can expect roots to establish in the first year, structural shoot development in the second, and full ornamental value from the third, underpinning long-term credibility for landscape and wholesale partners.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Groundcover rose, registered as NOAson, traded as Noasun Décorosiers® NOAson, also known in ARS exhibition use as Celina, positioned within the Décorosiers® collection for landscape and mass planting. |
| Origin and breeding |
Bred by Werner Noack in Germany before 1996 from ‘Immensee’ × ‘Westfalengold’; introduced by Noack-Rosen from 1997 with EU PVR in 1996 and US plant patent protection granted in 1998. |
| Awards and recognition |
Holds ADR recognition from 1999 and received the RHS Award of Garden Merit in 2012, underlining dependable garden and landscape performance with an emphasis on health and ease of cultivation. |
| Growth and structural characteristics |
Spreading groundcover shrub, typically 60–100 cm high with 60–110 cm spread, forming dense, glossy dark-green foliage; moderately thorny shoots create a tight, carpeting structure suited to covering soil areas. |
| Flower morphology |
Semi-double, flat, cluster-borne flowers with 13–25 petals and medium flower size around 1.5–2.75 inches, with good self-cleaning so most spent blooms drop naturally, maintaining a presentable canopy. |
| Colour data and phenology |
Medium-saturation yellow blooms with a subtle golden sheen, bright lemon buds and warmer yellow bases, gradually lightening to creamy pastel tones toward the edges and fading paler in stronger sunlight. |
| Fragrance and aroma |
Medium-strength, pleasant, non-intrusive scent with a soft, harmonious character; semi-double form offers partial pollinator value, though access to stamens and nectar is somewhat restricted by petal arrangement. |
| Hip characteristics |
Moderate production of small spherical hips, around 5–9 mm in diameter, usually green to reddish in colour; hips are visually discreet and do not dominate the plant’s overall ornamental presentation. |
| Resistance and winter hardiness |
Rated H7 with Swedish Zone 3 and USDA 6b performance, tolerating approximately -21 to -18 °C; resistant to black spot, powdery mildew and rust, with good tolerance of heat and moderate drought stress. |
| Horticultural recommendations |
Recommended for groundcover, flower beds, parks, urban green spaces and containers; designed for project mass planting via uniform, dense, bush-trained finished products with low maintenance needs from own-root stock. |
