DETROIT™ – red dwarf-mini rose – pharmaROSA® NEONATAL rooted cutting
Compact own-root DETROIT™ supports dense, upright mini-rose production for patio and small-space ranges where volume and predictable colouring matter. The strong, repeat-flowering habit in small 1.5–2 L containers enables fast, impulse-oriented turnover while maintaining medium maintenance needs and only occasional plant protection in nursery conditions. Its medium disease resistance with specific strength to powdery mildew and black spot helps maintain homogeneous batches and reduces unsaleable loss across cycles. With hardiness rated to RHS H7 and Swedish Zone 3, it is well suited to UK nursery networks needing reliable winter performance and flexible, logistics-friendly supply for climates where winter and wind exposure are common. Year 1 focuses on root establishment, Year 2 on structural shoot build-up, and by Year 3 DETROIT™ delivers its full ornamental value as a durable, own-root base for thematic and collection-style mini-rose assortments. The cluster-flowering, small, pompon blooms create an instant, long-lasting display in a limited footprint, aligning well with compact container – patio finished-product positioning and retail nursery routes seeking impulse colour, while the own-root form underpins long-term stability in stock stands and renewability for wholesale programmes.

| Origin and breeding |
Miniature, Hybrid Setigera rose with parentage not provided; breeding company, breeder, introduction and registration years not provided; breeding year indicated as 2000, with initial distributor data not provided. |
| Growth and structural characteristics |
Upright growth to about 100–120 cm height and 70–90 cm spread, forming a compact, dense bush with moderately thorny shoots; foliage moderately dense, slightly glossy, dark green, contributing to a neat, small-footprint habit. |
| Flower morphology |
Small S-class blooms (approx. 0.5–1.5 in) in clusters, spherical pompon shape, double flowers with 26–39 petals; strongly repeat-flowering with an abundant second flush, designed primarily for ornamental rather than pollinator-focused use. |
| Colour data and phenology |
Bright scarlet-red buds open to uniform scarlet flowers with a warm orange base and cooler carmine edges, later softening to brick–mahogany with pinkish-brown margins; colour retention medium, full bloom appearing fiery red in strong light. |
| Fragrance and aroma |

| Hip characteristics |
Occasionally forms small, spherical hips about 11–13 mm in diameter, bright red and visually attractive; hip production is secondary to the main flowering display and does not significantly affect plant habit or maintenance. |
| Resistance and winter hardiness |
Disease resistance medium overall, with resistance to powdery mildew and black spot and medium response to rust; cold tolerant to about -21 – -18 °C, rated RHS H7, Swedish Zone 3, USDA Zone 6b, supporting robust outdoor cultivation. |
