Shrub Rose Cardinal de Richelieu A beautiful, summer-flowering Gallica rose, Rosa Cardinal de Richelieu is a medium-sized, deciduous shrub rose with a compact, bushy habit and slender, almost thornless stems. The lush, divided leaves are mid-green. In midsummer, the shrub bears a profusion of gorgeous, almost globular, fully double, deep purple flowers which open out to a dusty purple with a pale centre and green eye; they have a deep, distinctive scent. For best flowering, apply fertiliser and a mulch in late winter or early spring. Shrub rose Cardinal de Richelieu tolerates poorer soil than most roses, and is a tough, hardy rose.
