BLUE GIRL – lavender-lilac hybrid tea rose – KORgi

This classic hybrid tea offers unusually refined colour in cool lavender-lilac tones, producing large, high-centred blooms that feel at home in both traditional and contemporary gardens. Bred for exhibition-standard flowers, it also performs dependably in ordinary beds and borders, provided you give it regular watering in dry spells and avoid prolonged drought. Its upright, bushy habit makes it ideal as a focal plant near a path or front door, where the strong, sweet fragrance can be enjoyed on summer evenings. Own-root planting supports a long-lived, balanced structure, steadily building into a reliable presence that responds well to simple, once-a-year pruning. Over the first few seasons you will see a natural progression – first roots, then stronger shoots, and by the third year a full display of elegant, scented flowers.

Usage options

Target area Reasoning
Front garden focal point Use as a stand-alone specimen by a gate, path or bay window, where its upright form and extra-large, exhibition-style blooms create an instant point of interest without needing complex planting schemes – ideal for beginners.
Cutting patch or cutting corner Plant 3–5 bushes together in a sunny strip to produce long, straight stems with high-centred, double flowers that last well in the vase, letting you cut scented bunches regularly through summer – perfect for the home florist.
Small mixed border with perennials Combine with cottage perennials in a modest border, where the pastel lavender-lilac tones blend gently with blues and soft pinks, giving repeat flushes of flower that add structure between seasonal perennials – reassuring for the style-conscious novice.
Near seating or terrace Place close to a bench or patio so the strong, sweet fragrance can be appreciated at nose height, while the tidy, upright bush keeps surrounding paving clear and needs only straightforward winter pruning – convenient for the relaxed garden user.
Formal pair by a path or entrance Plant as a matching pair to frame steps or a path, where the regular bushy habit and repeat flowering give a composed, formal look without intricate clipping, helping maintain a smart front garden with minimal decisions – helpful for time-pressed owners.
Feature in cottage-style planting Thread through a cottage-style mix with grasses and shrubs, where its long-lived, own-root framework quietly anchors the planting and integrates well over the years, supporting a stable, low-fuss layout – reassuring for long-term garden planners.
Large container on patio or balcony Grow in a substantial 40–50 litre container with good drainage, where regular watering and feeding are simple to manage, and the upright, sparsely thorned stems stay manageable and easy to tend at arm’s reach – suitable for small-space gardeners.
Bed in exposed or open-plot settings Use in open, breezy beds where its medium disease resistance and resilient growth handle typical British weather, provided watering is maintained during dry spells and soil drains freely after heavy rain – practical for everyday family gardens.

Styling ideas

  • COTTAGE BLEND – Mix with soft pink roses, lavender and catmint for a pastel, airy border that showcases the silvery blooms – for lovers of informal, romantic cottage gardens
  • CLASSIC CUTTING – Arrange a short row in a sunny strip backed by a simple green hedge, giving easy access to straight stems for vases – for home decorators who like fresh flowers indoors
  • FRAGRANT SEAT – Flank a garden bench with two plants underplanted with low-growing thyme, so scent rises around the seating area – for those who unwind outdoors after work
  • MODERN ENTRY – Plant in tall, simple containers by the front door with silver grasses, linking traditional rose beauty to a clean, contemporary façade – for design-aware urban homeowners
  • PASTEL FRAME – Use a trio in front of darker shrubs to frame a view, their lavender-lilac flowers brightening the line of sight – for gardeners wanting gentle structure without rigid formality

Parameter Data
Name and registration Hybrid tea rose, registered as KORgi, traded as Blue Girl Hybrid tea rose KORgi; ARS exhibition name Kölner Karneval, from the Hybrid Tea commercial group.

Awards and recognition Recognised for its ornamental quality with a Rome Gold Medal in 1964, supporting its standing as a classic hybrid tea suited to both gardens and exhibition use.

Fragrance and aroma Strong, sweet, perfumed scent typical of classic hybrid teas, lingering well on the plant and in cut stems, ideal where fragrance is a key priority in garden or vase.
Hip characteristics Forms small, ovoid, orange-red hips 12–18 mm across, only occasionally produced, giving light seasonal interest without significantly affecting ornamental flower performance.
Resistance and winter hardiness Hardy to about −21 to −18 °C (RHS H7, Swedish zone 3, USDA 6b); good resistance to powdery mildew and black spot, moderate susceptibility to rust, needs regular watering in heat.
Horticultural recommendations Best in full sun with moist, well-drained soil; medium maintenance with some pest control and deadheading; suitable for beds, specimens, hedging rhythms and larger containers from 40 litres.

Information about the videos
The video series is not a “seasonal showcase”; it illustrates the essence of pharmaROSA® own-root cultivation in a tangible way: how the plant is built up, what the root system is like and how the shoot system regenerates. The recordings were therefore made at different times and with plants at various stages of development, so mixed foliage levels and differing stages of growth may appear in the videos. They are not a ‘sample’ of the batch dispatched, but a visual explanation of how the technology works. The current condition of the rose available to order — typical for the given period and similar to what you can expect to receive in the parcel — is shown in the upper part of the product page.
