Ena Harkness™ – pharmaROSA® NEONATAL rooted cutting for premium hybrid tea production
Fragrance and flower quality make Ena Harkness™ a reliable choice where classic hybrid tea presentation and cutting-stem value matter, supported by own-root stability for long-term border and specimen stands. As a remontant hybrid tea with medium maintenance needs and a bush-trained release form, it fits smoothly into premium container production targeting 5–7 L formats and exclusive retail / reseller channels. Its upright, moderately leafy framework and solitary, velvety-scarlet blooms with very strong perfume offer a recognisable, historic exhibition profile suited to curated collections and thematic rose gardens, while its H7 hardiness and Swedish zonal rating help manage exposure in cooler UK regions with winter and wind-tolerant reliability. Own-root vigour supports a predictable development arc from strong roots in year one, structural shoots in year two, and full ornamental value from year three, aligning with nursery planning and capacity scheduling for premium specimen and cut-flower orientated lines. Although self-cleaning is weak and occasional disease control is advisable, the predictable remontant flush and strong colour retention at retail-ready stage help underpin credibility in trade-facing ranges and collection-led programmes.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose cultivar Ena Harkness, commercial type and group hybrid tea rose, current trade name Ena Harkness™ Hybrid tea rose Ena Harkness, ARS exhibition name Ena Harkness, unregistered but widely established in commerce. |
| Origin and breeding |
Bred by Albert Norman in the United Kingdom from ‘Southport’ × ‘Crimson Glory’, breeding and introduction year 1946, initially distributed by R. Harkness & Co. Ltd., representing a classic mid-twentieth-century exhibition hybrid tea lineage. |
| Awards and recognition |
Recognised historically with RNRS Gold Medal in 1945 and Portland Gold Medal in 1955, maintaining ongoing relevance in exhibition and collection contexts where classic hybrid tea form and strong fragrance remain valued criteria. |
| Growth and structural characteristics |
Upright habit reaching approximately 70–100 cm in height with 50–70 cm spread, moderately dense, slightly glossy dark green foliage and a densely thorned framework, forming a structured bush suitable for border, specimen and premium container roles. |
| Flower morphology |
Double, medium-sized hybrid tea blooms with 26–39 petals, solitary on stems, cup to goblet shaped, remontant with an abundant second flush, providing repeated ornamental value and cutting stems when managed within premium production systems. |
| Colour data and phenology |
Velvety deep scarlet with subtle black undertone; ARS dr, RHS 53A outer and 46A inner, buds dark burgundy; intense scarlet on opening, softening to matte crimson, colour lightens slightly in strong sun but remains deep red in cooler conditions. |
| Fragrance and aroma |
Very strong, garden-filling fragrance with a full, classic rose scent profile, providing high sensory impact in borders, specimen plantings and cut stems, though the highly double, closed flower form limits pollinator access and ecological contribution. |
| Hip characteristics |
Hip set is limited due to the double flower form, with occasional red, ovoid hips approximately 12–16 mm in diameter where pollination occurs, contributing minor seasonal interest rather than being a primary production or display feature. |
| Resistance and winter hardiness |
Moderate disease resistance to powdery mildew, black spot and rust, with medium maintenance needs and occasional plant protection recommended; hardy to approximately -21 to -18 °C, RHS H7, Swedish Zone 3 and USDA Zone 6b under appropriate culture. |
| Horticultural recommendations |
Best used as border, cut-flower and specimen material, grown as bush-trained plants with 3–5 framework canes, following a premium container path; own-root NEONATAL cuttings suit nursery propagation beds and collection or retail-stock building. |
Ena Harkness™ offers strong fragrance, classic hybrid tea form and robust hardiness on a predictable own-root base, making it a sound option for premium, homogeneous container and collection production; please feel free to discuss volumes and scheduling.
