SUPER EXCELSA – crimson-red climbing rambler rose - Hetzel
If You dream of a cheerful, cottage-style entrance, Super Excelsa offers a cascade of small crimson blooms that transform walls, arches and fences into a romantic curtain of colour. Its semi-double clusters create charming texture, while dense, dark green foliage gives reliable coverage even when not in flower. This vigorous rambler is surprisingly easy to manage once established, suiting Irish gardens that regularly face rain and soft winds by the coast and inland. Own-root plants settle in steadily for impressive longevity, and if You give them good drainage and a mulch, they reward You with stable ornamental impact over the years. With a once-a-year summer flush that lasts for weeks, it shines as a seasonal spectacle along paths and terraces, bringing a mood of soft, green light and contentment to everyday garden life.
Usage options
| Target area | Reasoning |
|---|
| Cottage-style arch over a garden path |
The long, flexible canes and dense flowering make this rose ideal for clothing an arch, creating a tunnel of colour and shade in early summer. Its vigorous growth quickly knits into supports, forming a romantic focal point for walkers and passers-by, appealing particularly to the cottage-garden enthusiast. |
| Family boundary fence or wire trellis |
With a spread of up to 3 m and strong climbing habit, it provides generous coverage on fences and wire, helping to soften boundaries and increase privacy. Once trained, maintenance is modest, mainly light pruning and the odd tie-in, suiting the busy-homeowner gardener. |
| House wall or garage gable with support |
This climber copes well with partial shade beside buildings, its dark foliage and crimson clusters brightening dull walls. In Ireland’s changeable weather it remains reliable, even where summers are short and breezy, which reassures the urban-terrace gardener. |
| Pergola or seating area canopy |
Super Excelsa’s strong growth can be guided over a pergola to provide dappled shade and a delightful overhead flowering curtain in early summer. Moderate prickliness and tidy foliage make it pleasant around seating, a boon for the outdoor-living family. |
| Informal flowering hedge or screen |
Planted at hedge spacing, its arching canes and clusters of small flowers create an informal, wildlife-friendly screen. Occasional orange-red hips add seasonal interest, making it a good choice for those who enjoy subtle nature detail, such as the pollinator-minded gardener. |
| Dublin terraced-house front garden feature |
Trained up a narrow trellis or porch, it delivers strong vertical colour in small footprints. Own-root plants establish steadily, with roots strengthening first, then more shoots, and by the third year giving full ornamental value, suiting the patient city-front-garden owner. |
| Large obelisk in lawn or border |
Its height and cluster-flowered display turn a tall obelisk into a dramatic summer column, while semi-double blooms still offer some interest for insects. Good for adding height without complex care, this suits the beginner hobby-gardener. |
| Mixed shrub and rose border backdrop |
Behind lower perennials and shrubs, the crimson-red flush becomes a seasonal backdrop, then the glossy foliage keeps structure. Suitable for clay soils if You ensure drainage and mulch, making it practical for the nature-loving Irish homeowner. |
Styling ideas
- Cottage Arch Romance – Let Super Excelsa drape over a metal or wooden arch, underplant with foxgloves and hardy geraniums for a soft, storybook entrance – ideal for nostalgic cottage-garden lovers.

- Wildlife-Friendly Screen – Use as an informal screen with dogwood ‘Midwinter Fire’ and woodland sage in front, adding colour and hip interest for birds – great for quietly wildlife-minded gardeners.
