BLACK FOREST ROSE® – pharmaROSA® NEONATAL rooted cutting for professional production
As a compact, bushy floribunda from the RigoRosen® collection, BLACK FOREST ROSE® offers reliability in nursery systems that need uniform, repeat-flowering material for standard container lines and bedding schemes; its own-root longevity supports long-term stock blocks and low replacement in themed and municipal rose collections. The dense, glossy dark foliage and colour-stable, bright red clusters create a strong, recognisable flower-bed identity suited to retail ranges built on reliable garden performance, while the ADR-rated health profile and H7 hardiness give confidence for production supplying cooler, wind-exposed UK regions with dependable landscape value. Medium maintenance needs, good self-cleaning habit and compact plant architecture fit efficiently into 2–3 L standard containers as a finished product route or as semi-finished tray-rooted cuttings for further potting on towards 40–50 L landscape formats. Own-root regeneration under repeated trimming and crop cycles supports homogeneous stands and predictable capacity across nursery networks, while the partially pollinator-friendly flower clusters and discreet hip set suit public-realm schemes focused on biodiversity accents without heavy fruit load. With an upright, ground-cover-capable structure and a development rhythm where roots establish first, shoots build in the second year and full ornamental effect follows from the third, this cultivar aligns well with professional scheduling for exhibition floribunda / bush rose assortments.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Floribunda bed rose marketed as Black Forest Rose® (RigoRosen®), registered as KORschwill; exhibition floribunda / bush rose category with American Rose Society name Black Forest Rose. |
| Origin and breeding |
Bred by Tim-Hermann Kordes at W. Kordes’ Söhne from unnamed seedling parents; introduced and registered in 2010 by W. Kordes’ Söhne in Germany for international distribution. |
| Awards and recognition |
Holds ADR 2010 designation plus multiple awards, including 1st prize Baden bei Wien 2010, gold medals Kortrijk/Courtrai 2011 and 2012, RNRS Trial Ground Certificate 2011, and La Tacita recognition. |
| Growth and structural characteristics |
Bushy, upright habit to about 65–95 cm high and 55–85 cm wide, moderately thorny, with dense, glossy dark green foliage delivering compact, well-filled plants suitable for bedding and container formats. |
| Flower morphology |
Semi-double, medium-sized cluster-flowered blooms with roughly 13–25 petals and cup-shaped form; remontant with a plentiful second flush, giving continuous decorative impact in beds and amenity plantings. |
| Colour data and phenology |
Bright, saturated red flowers (ARS MR, RHS 46A–46B) with excellent colour retention, minimal fading and a slight maroon tone at senescence; colour remains uniform across the plant through flowering cycles. |
| Fragrance and aroma |
No noticeable scent, classified as an unscented rose; semi-double blooms with exposed stamens offer some pollinator value despite the lack of fragrance, making it a visual rather than olfactory feature plant. |
| Hip characteristics |
Occasionally forms small spherical hips, about 6–10 mm diameter, in orange-red RHS 40A; quantities remain low because of effective self-cleaning, so hips rarely dominate the overall ornamental appearance. |
| Resistance and winter hardiness |
Hardy to around -26 to -23 °C (RHS H7, Swedish zone 4, USDA 5b); good heat tolerance with short dry-spell resilience, resistant to black spot and rust, moderate against powdery mildew, needs irrigation in long droughts. |
| Horticultural recommendations |
Suited to flowerbeds, parks, urban green spaces, ground-cover and edging; medium maintenance with occasional pest control, self-cleaning spent blooms, best as bush-trained compact plants in standard 2–3 litre containers. |
BLACK FOREST ROSE® (KORschwill) combines compact, award-backed floribunda performance with durable, own-root longevity and predictable regrowth, making it a sound choice for stable, large-scale programmes where we can align capacity and scheduling together.
