When a rose is grown in this way, it allows the development of magical garden scenes as neighboring plants clamber and crawl over and around these horizontal stems. Good plants to pair with roses in this way will have an open and accommodating growth habit which doesn't mind the extra support and constraint from the lattice of canes that develop, yet don't overwhelm the rose and inhibit good air flow around the plant (an important disease prevention measure). Some choice plants to try: clematis (naturally!), salvia, nepata, agastache, allium, lilies, and many more.
Most importantly, have fun, PLAY and make some captivating combinations in your own garden this summer!
