This form of wild rose, first collected in its native Japan, has several cultivars which are commonly
grown as rambling roses, suitable for planting as climbers in the protected garden in Arriyadh.
With a rapid growth rate, this dense and vigorous, vine-like shrub forms green highly pliable
stems up to 6 metres long. It has glossy, leathery leaves 5 to 10 cm long with seven leaflets, and
rich, long-lasting, inflorescences composed of fragrant, apple-scented panicles of small, white
flowers with five petals and prominent yellow stamens. These are followed by dark-red, rose-hip
fruits. This rose will grow in most fertile, well-drained garden soils in full sun, and is very frost
hardy. Slightly drought-tolerant, the rose benefits from deep watering every three to four weeks in
summer. Fertilising should be done at the beginning of the growing season, with mature manure
around the base of the rose canes every two to three years. They require pre-emptive treatment
with insecticide and systemic fungicide to prevent attack by aphids and the development of fungal
diseases. Rambling roses require more than a trellis for support. They are excellent on the side
of a building, fence or shade structure, but require securing on stakes and strong fastening to
structures. They will also grow into the branches of a tree when planted close together, which
means that a non-blooming tree appears to bear flowers. This a plant with high maintenance
requirements, best suited to a plant enthusiast’s private garden.
