Noteworthy CharacteristicsRugosa roses have thorny branches and attractive, distinctively wrinkled leaves. (The species takes its name from the Latin word rugosus , meaning "full of wrinkles".) They grow well in mixed borders, hedges, and as specimens. They are tolerant of harsh conditions, including salt spray, wind, and poor soil. 

CareGrow in fertile, moist, well-drained soil in full sun or partial shade. Provide good air circulation and remove fallen leaves to help prevent disease. In late winter or early spring, prune lightly or back by up to one-third, reducing side shoots by one-half to one-third. To renovate, prune one in four or five shoots at the base.

PropagationTake softwood cuttings when bloom initiates in spring to summer; take hardwood cuttings in fall. Sow seeds of species in fall and bud in summer.
