Rosa rugosa is a tough, easy to grow rose bearing pink, scented blooms followed by bright scarlet hips. Its dense, vigorous growth and prickly stems make it perfect for hedging. For best results grow Rosa rugosa in moist but well-drained soil, in full sun. As a shrub rose, it’s best pruned in late summer, after flowering has finished. Prune most stems lightly. To encourage young, vigorous growth, cut back a few of the oldest stems each year.
