BLUE GIRL – lavender-lilac hybrid tea rose - Kordes
Premium own-root pharmaROSA® NEONATAL material of Blue Girl (KORgi) supports exclusive container and cut-flower programmes where colour distinctiveness and flower quality are central. As a remontant, high-centred, XL-flowered hybrid tea with strong, lasting fragrance, it delivers reliable stems for exhibition-type cut production and visually striking 5–7 L premium pots. Upright, bushy habit with medium-dense, matt mid-green foliage and sparse prickles helps maintain clean, saleable crowns in nursery beds and container lines. Own-root structure offers long-term stability, renewable growth and homogeneous stands, reducing replacement in collection and show-garden plantings. Medium disease resistance with good black-spot and powdery mildew performance supports predictable scheduling in UK networks, even where winters are cold and windy. With maintenance rated medium and occasional pest control, it fits professional systems aiming for strong visual impact and reliable repeat flushes. Year by year, roots establish first, then framework shoots, before full ornamental performance is expressed from the third season, aligning well with multi-year nursery planning for wholesale and retail/reseller channels.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose, registered as KORgi, traded as Blue Girl hybrid tea rose KORgi; ARS approved exhibition name Kölner Karneval, in the hybrid tea exhibition and cut-flower categories. |
| Origin and breeding |
Bred by Reimer Kordes, W. Kordes’ Söhne, Germany, from ‘Magenta’ × ‘Sterling Silver’; bred, registered and introduced in 1964 with initial distribution via Star Roses and Plants and W. Kordes’ Söhne. |
| Awards and recognition |
Rome Gold Medal 1964 underscores historic recognition for its ornamental qualities, particularly flower form and overall performance within its hybrid tea class and exhibition use. |
| Growth and structural characteristics |
Upright, bushy hybrid tea growing 110–150 cm high and 75–105 cm wide, with moderately dense, matt mid-green foliage and sparse prickles; self-cleaning is weak, so spent blooms need manual removal. |
| Flower morphology |
High-centred, pointed-budded double flowers with 26–39 petals, XL size from about 3.5 inches upwards, usually solitary on stems, well adapted to cut-flower and exhibition-type hybrid tea presentation. |
| Colour data and phenology |
Lavender-purple to lavender-lilac blooms, RHS 76C/76A; colour shifts from frosted silvery-lilac buds through pastel lavender-pink to dusky rose-grey tones, with some fading in heat and strong sun. |
| Fragrance and aroma |
Strong, long-lasting sweet, perfumed fragrance characteristic of scented hybrid teas; double blooms partly conceal stamens, so the cultivar is valued primarily for ornamental and sensory display, not pollinator support. |
| Hip characteristics |
Occasional small, ovoid hips 12–18 mm in diameter, orange-red when ripe; hips are not a dominant ornamental feature but may appear sporadically following flowering cycles. |
| Resistance and winter hardiness |
Medium overall disease resistance, with resistance to powdery mildew and black spot but medium susceptibility to rust; hardy to about –21 to –18 °C, classified RHS H7 and Swedish hardiness zone 3, USDA zone 6b. |
| Horticultural recommendations |
Suited to flower beds, specimen use, containers and cut flowers; medium maintenance and occasional pest control; bush-trained, 3–5-cane form recommended for premium container production in 5–7 L pots. |
