GRANDESSA – deep red climbing rose – Delbard
With GRANDESSA you can bring a romantic, storybook cottage mood to your family garden, creating a shady nook for afternoon tea beneath a rose-covered arbour. This Delbard-bred climber carries velvety, high-centred, deep-red blooms that repeat through the season, setting a dramatic backdrop against glossy dark foliage. Once established, its strong framework anchors reliably in breezier spots, even where gardens face regular rain and wind along more exposed coastlines. As an own-root plant in the pharmaROSA ORIGINAL 2-litre container, it settles quickly and is built for a long garden life, regenerating well from the base and keeping its ornamental value over time. Give it a simple support on a wall, fence, or arch and enjoy dependable flowering with only moderate care. In its first year it concentrates on roots, the second on stronger shoots, and by the third season you see its full character as a mature climber. Ideal for “girly”, English countryside borders, it pairs beautifully with pale perennials and a traditional kitchen-garden feel.
Usage options
| Target area |
Reasoning |
| Pergola or arbour in a family garden |
Trained over a pergola or arbour, GRANDESSA quickly forms a leafy, flower-laced canopy that makes afternoon seating areas feel enclosed and cosy. Its moderate care needs suit those wanting romance without complex pruning, perfect for the busy homeowner. |
| Climbing rose on a sunny house wall |
On a south- or west-facing wall, its deep-red, high-centred blooms read clearly from a distance, adding classic structure and colour to typical brick or render. Own-root resilience helps it recover from occasional neglect, ideal for the time-pressed gardener. |
| Fence cover between neighbouring gardens |
Used along a boundary, its dense, glossy foliage and repeat flowers soften panel fencing while offering a gentle visual screen. The strong framework and good anchoring suit more exposed, rain- and wind-prone suburban plots, reassuring the family buyer. |
| Cottage-style rose border with perennials |
Grand, velvety blooms combine beautifully with soft pinks, whites and airy companions for a romantic cottage effect. Reliable repeat flowering through summer keeps borders lively without demanding intricate care, attractive for the cottage-style enthusiast. |
| Traditional kitchen garden entrance or arch |
Trained over an entrance arch into a kitchen garden, its rich colour frames views and lends a “storybook” feel. The own-root habit offers a long working life with simple renewal pruning, which suits the practical home grower. |
| Large container or half-barrel near a terrace |
In a 40–50 litre container with good drainage and a sturdy obelisk, GRANDESSA delivers vertical colour where borders are limited. Moderate feeding and watering are usually enough for steady growth, appealing to the small-garden owner. |
| Feature rose on a rustic trellis or screen |
Its height and strong, creeping habit make it effective on rustic trellis, turning plain structures into focal points. The long-lived own-root base means the trellis can be clothed for many seasons, a benefit valued by the long-term planner. |
| Showpiece near seating for evening enjoyment |
Placed by a terrace or bench, the velvety deep-red flowers and mild, pleasant fragrance are easy to appreciate at close range. The development arc from year 1 roots to year 3 fullness rewards patience, suiting the romantic gardener. |
