ILSE KROHN SUPERIOR® – white climbing rose – Kordes
Step out to your front door for a few quiet minutes and let Ilse Krohn Superior® frame your walk with cascades of pure white flowers, even when summer feels short and the weather brings showers and soft wind from the Atlantic. This reliable climbing rose forms an elegant, leafy screen with a gently fresh fragrance, ideal for softening walls or adding romance to a Dublin terrace. Its own-root nature means long-lived stability, steady regrowth after pruning and fewer worries if a stem is damaged. Give it good drainage in Irish clay, a simple yearly feed and light pruning, and it will reward you with repeat flowering and long-lasting snow-white blooms. Expect your rose to focus on roots in year one, build strong shoots in year two and reach full ornamental impact by year three, settling beautifully into a “girly” cottage-garden scene.
Usage options
| Target area | Reasoning |
|---|
| Sunny house wall in a small or medium family garden |
This climber’s moderate height and dense foliage make it perfect for softening a front or back wall without overpowering a modest Irish garden. Once settled, it provides reassuringly consistent growth over many years with minimal fuss for the homeowner. |
| Irish cottage-style pergola or arbour |
The arching canes and repeat flushes of white flowers create a romantic tunnel effect over a pergola or arbour, evoking classic cottage gardens. With patient tying-in and simple annual pruning, it forms a long-lived framework for the cottage-gardener. |
| Dublin terraced-house front garden boundary |
Trained on wires or a narrow trellis, the dense dark green foliage provides an attractive vertical screen without taking much ground space, ideal for compact city plots. Occasional pruning keeps it tidy for the urban-gardener. |
| Feature climber on a sturdy pillar or obelisk |
Its climbing habit and medium-length canes can be wrapped around a strong pillar or obelisk, delivering a tall, white flowering column that anchors small to medium gardens. Once established, it remains structurally reliable for the design-conscious. |
| Mixed border backdrop with perennials |
Placed at the back of a border, it offers a calm, snow-white background that sets off cottage perennials such as campanulas and feverfew. This steady visual anchor reduces the need for frequent border redesign for the busy-gardener. |
| Partially shaded side passage or gable end |
This rose tolerates partial shade, so it suits side passages or gables that lose direct sun for part of the day, especially in damp, breezy Irish conditions with frequent rain and salt-tinged wind. This flexibility helps the space-limited town-dweller. |
| Cutting patch or picking corner |
The high-centred, double blooms are well suited for cutting, bringing elegant white stems indoors. Regular picking doubles as deadheading, keeping the plant flowering and reducing maintenance for the flower-lover. |
| Long-term, low-fuss structural planting |
As an own-root climber, it regenerates well from the base, so if an old cane is removed or winter damage occurs, new shoots take over and keep the plant ornamental for decades, supporting gardeners who want enduring value with little replacement for the beginner. |

| Name and registration |
Hybrid Kordesii climbing rose; registered as Ilse Krohn Superior, also traded as Ilse Krohn Superior® climbing rose; exhibition climbing rose suitable for large-flowered show and cutting. |
| Origin and breeding |
Spontaneous mutation of ‘Ilse Krohn’ (Golden Glow × Rosa kordesii), bred by Reimer Kordes, W. Kordes’ Söhne, Germany; introduced and registered in 1964 as an improved white climber. |
| Growth and structural characteristics |
Strong climbing habit, typically 250–380 cm high and 170–240 cm wide, with dense, slightly glossy dark green foliage and moderate prickliness; weak self-cleaning so spent blooms benefit from deadheading. |
| Flower morphology |
Double, high-centred, pointed-budded flowers with 26–39 petals, medium-sized at 4–7 cm, borne mainly in clusters; remontant with particularly abundant second flush when regularly pruned and fed. |
| Colour data and phenology |
Pure, uniform snow-white blooms with occasional faint creamy centre; silvery, pearlescent sheen in sunlight and very good colour retention, with only slight petal-edge browning in strong sun as flowers age. |
| Fragrance and aroma |
Mild, fresh rose fragrance of restrained intensity; perceptible at close range without overwhelming seating areas or small terraces, making it suitable near doors, paths and frequently used garden spaces. |
| Hip characteristics |
Low hip set due to double flowers; any produced are spherical, orange, around 15–22 mm in diameter, adding discreet late-season interest without significant self-seeding or maintenance concerns. |
| Resistance and winter hardiness |
Hardy to about −26 to −23 °C (RHS H7; USDA 5b, Swedish zone 4); medium resistance to black spot, mildew and rust, benefiting from good air circulation, drainage and seasonal preventative care. |
| Horticultural recommendations |
Best on fertile, well-drained soil; space 140–250 cm depending on use. Train and prune annually, feed in spring, water during prolonged dry spells; suitable for partial shade and structural garden roles. |
Ilse Krohn Superior® offers long-lived structure, repeat white flowering and gentle fragrance, and in own-root form it regrows reliably from the base, making it a considered choice for your next climbing rose.
