BLEU MAGENTA – purple rambler climbing rose
If You dream of a romantic, cottage-style climber that will simply settle in and get on with the job, Bleu Magenta offers a cascade of small, cupped purple blooms in dense clusters, creating an unforgettable display along walls, arches or pergolas. This once-flowering rambler covers itself in very double, chalice-shaped blossoms that soften from rich violet to misty mauve as they age, giving Your garden a gently evolving colour story without constant deadheading. Its climbing habit is naturally graceful yet manageable, and the moderately thorny canes are easy to tie in and train. Hardy and long-lived on its own roots, it settles deep into the soil and copes reliably even where heavy rain and cool winds bring increased fungal pressure. The glossy dark green foliage stays attractive all season, making it just as valuable after flowering as during its peak show. In year one it concentrates on roots, year two brings stronger shoots, and by year three You can expect its full ornamental impact across Your trellis or boundary.
