GRANDESSA – deep red climbing rose – Delbard
If You dream of a romantic climbing rose that simply fits into Irish family gardens, GRANDESSA gives You a tall, richly foliaged backdrop of velvety deep-red blooms with remontant flowering from early summer into autumn. Its stems reach pergolas, arches or fences without demanding complicated pruning, creating structure and privacy around your home while coping well with Ireland’s damp air and humidity-driven disease pressure. The glossy dark green foliage sets off the dramatic, high-centred, cut-rose style flowers, so even a single plant feels like a showpiece by the front door. As an own-root climber, it forms a stable, long-lived framework that can regenerate from its base, giving lasting confidence for beginners who want a reliable, premium Delbard rose. In year one it builds roots, in year two it extends its shoots, and by year three it reaches its full ornamental impact as a mature garden presence.
