Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose registered and marketed as Diamond Jubilee, with Hybrid tea commercial grouping; own-root NEONATAL material supplied as verified cultivar-true propagation stock for nursery and wholesale production uses. |
| Origin and breeding |
Bred by Eugene S. Boerner for Jackson & Perkins Co. in the United States, introduced in 1947 from the cross ‘Maréchal Niel’ × ‘Feu Pernet-Ducher’ as a commemorative cultivar; supplied here as unbudded own-root material. |
| Awards and recognition |
Holder of All-America Rose Selections distinction in 1948 and protected under US Plant Patent 824 (1949), underpinning its historic reputation for ornamental and cut-flower quality within hybrid tea rose breeding. |
| Growth and structural characteristics |
Upright hybrid tea shrub reaching about 100–140 cm in height with 60–80 cm spread, moderately thorny, medium-dense matt mid-green foliage; spent blooms persist and require deadheading to maintain display and plant health. |
| Flower morphology |
Medium-sized, double, high-centred hybrid tea blooms with 26–39 petals carried mainly singly; pointed, cut-rose type buds give a formal, exhibition-style effect, and the plant repeats well with a notably abundant second flush. |
| Colour data and phenology |
Light-yellow to pale butter-yellow flowers with soft peach shading, ARS ly; RHS 11C outer and 15D inner, fading in sun toward creamy white, sometimes with slight pinkish tints, offering an elegant, pastel-toned presentation in beds. |
| Fragrance and aroma |
Fresh, fruity fragrance of medium strength, clearly noticeable on open blooms; flower structure prioritises ornamental and exhibition value rather than pollinator access, so ecological contribution in this respect is limited. |
| Hip characteristics |
Hip set is generally low due to very double blooms; where formed, hips are small, globular, orange-red, around 10–14 mm diameter and mainly of visual interest rather than a planned production feature. |
| Resistance and winter hardiness |
Hardy to approximately –21 to –18 °C (RHS H7, USDA 6b, Swedish zone 3) with moderate overall disease resistance; black spot and rust are moderate, powdery mildew very susceptible, requiring integrated protection in professional systems. |
| Horticultural recommendations |
Suited to flower-bed and cut-flower use with medium maintenance demands; prefers regular watering in heat, benefits from deadheading and scheduled plant protection; best positioned in premium container programmes using own-root crops. |
Diamond Jubilee offers repeat-flowering, high-centred pastel blooms, recognised historic status and reliable cold-hardy performance on long-lived own-root stands; we would welcome a discussion to align volumes and scheduling to your programme.
