OKLAHOMA™ – pharmaROSA® NEONATAL own-root hybrid tea rose propagation material

Oklahoma is a premium hybrid-tea cutting option for nurseries aiming to build high-value, exhibition-grade container crops and exclusive dark-red hybrid tea assortments from a reliable own-root propagation base. The very strong, classic rose fragrance and large, high-centred, solitary blooms support an exclusive finished-product positioning where flower form and showbench suitability are central. Upright, bushy growth with dense, dark-green foliage and 3–5 strong framework canes lends itself to premium 5–7 L production, with scope to move selected material into 40–50 litre statement pieces for thematic or collection plantings. As own-root pharmaROSA® NEONATAL material, it supports predictable, homogeneous stands and low replacement rates over time, supporting nursery network supply where winter and wind tolerance are required across cooler UK regions. Development typically moves from root build-up in year one, through structural shoot formation in year two, to full ornamental expression by year three, aligning well with planned premium release windows.

Usage options

Target area	Reasoning
Premium 5–7 L exhibition-grade containers	The combination of very double, high-centred blooms and solitary presentation makes OKLAHOMA™ a strong candidate for premium containers where flower quality and form must justify higher price points. Bush-trained plants with 3–5 framework canes fill 5–7 L pots efficiently, delivering the vertical presence expected of exhibition hybrid teas. Medium maintenance demands with occasional pest and disease control are manageable within high-value lines, while own-root physiology supports longer sales windows and reduced loss rates. This suits an exclusive finished product routed through retail and reseller partners targeting discerning rose buyers and specialist retail.
Feature plants in 40–50 L for thematic rose gardens	Upright, bushy growth to 130–170 cm with dense foliage enables up-potting selected plants into 40–50 L units for statement use in thematic or collection rose gardens. The dark burgundy-red colour and very strong fragrance create focal points that curate well in show gardens or institutional plantings. Own-root material tolerates long-term regeneration and restructuring pruning, essential where plants are maintained as permanent features. With a premium container product path and exclusive positioning, this format serves curated displays supplied via professional nursery networks and project wholesalers.
Cut-flower oriented retail rose lines	High-centred, cut-rose-type blooms with large flower size and solitary stems translate into an attractive garden rose for customers who also value occasional cutting for the vase. The remontant habit with a generous second flush provides repeat picking potential once established, aligning with premium-label messaging around flower performance. Bush-trained plants finished in 5–7 L pots can be marketed with clear cut-flower crossover, while own-root stability under repeated cutting supports predictable stand performance. This aligns with exclusive finished products marketed through retail and reseller channels for cut-flower enthusiasts.
Fragrance-led premium assortment blocks	Very strong, garden-filling scent of classic rose character allows OKLAHOMA™ to anchor fragrance-themed ranges where olfactory performance is the key differentiator. Medium maintenance and moderate disease resistance suit professional programmes focused on quality rather than ultra-low input. Own-root material underpins long-lived, regenerating stock for repeated fragrance campaigns, supporting reliable volumes season after season. This fits a premium container route with clear fragrance messaging, ideal for retailers and resellers curating scented collections for rose connoisseurs.
Dark red colour-focus and collection concepts	The deep, velvety burgundy-red flowers with black undertones provide a consistent, recognisable colour signature for dark red or “velvet rose” themed collections. Although colour retention weakens towards brownish-red when fading, the overall effect remains dark, which is visually coherent in grouped plantings or coordinated benches. Own-root propagation secures genetic consistency and repropagation capacity, important in maintaining branded colour ranges. In premium 5–7 L containers, this supports exclusive finished products positioned through retail and reseller partners to colour-oriented collection buyers.
Show and exhibition pre-stock for specialists	With its history as an exhibition hybrid tea and gold-medal recognition, OKLAHOMA™ is suitable for nurseries supplying stock to exhibition growers and specialist collectors. The high-centred form and solitary, large blooms match show requirements, while the premium gold cultivar quality rating supports confident positioning. Own-root NEONATAL material gives a predictable base for multi-year preparation cycles, with year-by-year development from roots to structure to full show performance aligning with planned exhibition schedules. This supports premium container routes into specialist retail and show exhibitors.
Collection and gene-bank style plantings	Documented breeding origin, parentage and verified authenticity make OKLAHOMA™ well suited to cultivar collections, teaching gardens and gene-bank style stands, where identity and traceability are essential. Own-root propagation means the cultivar can be renewed from true-to-type vegetative material without graft-related variability, stabilising long-term living collections. Bush-trained plants from 5–7 L containers transition well into field beds for maintenance. This aligns with exclusive but technically documented finished stock supplied through nurseries serving institutional and collection-focused partners.
Public-realm statement pockets in cooler regions	Hardiness to approximately –21 to –18 °C, with H7 and Swedish zone 3 ratings, allows deployment in colder UK regions, supporting public-realm suppliers who need roses that will overwinter reliably where winter and wind exposure are normal. Own-root plants recover structurally after adverse seasons, holding stand density and reducing replacement cycles in higher-profile pockets such as civic rose beds or entry features. Finished in 5–7 L and, where required, 40–50 L containers, OKLAHOMA™ can be offered as an exclusive product through project-based resellers to municipal and institutional clients.

Technical cultivar profile

Name and registration	Hybrid tea rose cultivar Oklahoma, registered with the same name and marketed as Oklahoma™; American Rose Society approved exhibition name is Oklahoma, with verified cultivar authenticity and premium gold quality rating.
Origin and breeding	Bred in the United States in 1963 by Herbert C. Swim and O. L. Weeks at Oklahoma State University from ‘Chrysler Imperial’ × ‘Charles Mallerin’; introduced commercially in 1964 by Weeks Wholesale Rose Grower, Inc.
Awards and recognition	Recognised early in its career with a Gold Medal at the Tokyo Japan Rose Concours in 1963, reinforcing its suitability for exhibition use and supporting premium, show-oriented positioning in today’s assortments.
Growth and structural characteristics	Vigorous, upright bushy habit reaching around 130–170 cm high and 100–140 cm wide, with dense, slightly glossy dark green foliage and moderate prickliness; suited to bush training with 3–5 strong framework canes.
Flower morphology	Large-flowered, very double blooms with 40+ petals, presented mainly as solitary flowers on stems; classic high-centred, pointed-bud hybrid tea form associated with cut-rose types, supporting exhibition and feature use.
Colour data and phenology	Deep, velvety dark red with burgundy and black undertones; newly opened blooms are very dark, lightening moderately as they open, later shifting towards brownish-red yet generally retaining an overall dark visual effect.
Fragrance and aroma	Very strong, garden-filling scent of sweet, classic rose character; the highly double flower form prioritises ornamental and olfactory impact over pollinator access, making it a fragrance-led display and cut-flower subject.
Hip characteristics	Occasionally forms small, ellipsoid red hips around 12–18 mm in diameter; hips are incidental rather than a primary ornamental feature and generally secondary to the cultivar’s flower and fragrance display value.
Resistance and winter hardiness	Hardy to approximately –21 to –18 °C, aligned with RHS H7, Swedish zone 3 and USDA zone 6b; disease resistance is moderate, with powdery mildew, black spot and rust requiring periodic monitoring and control.
Horticultural recommendations	Best used as a premium container bush, especially in 5–7 L and larger pots, with medium maintenance and occasional plant protection; remontant with a generous second flush, supporting extended sales and display periods.

OKLAHOMA™ offers large, exhibition-quality dark red blooms, very strong fragrance and reliable cold-hardy performance on a predictable own-root base, making it a sound choice for premium programmes where we can jointly plan capacity and timing.
