Rosa rugosa (RO-za ru-GO-sa)

Family: Rosaceae Non-native Shrub (3-15 ft)

Rugosa rose is a hardy, multi-stemmed, disease-resistant deciduous suckering shrub rose in the Rosaceae family that is native to eastern Asia, in northeastern China, Japan, Korea and southeastern Siberia. The epithet, rugosa , is translated as "wrinkled" and references the appearance of the leaves The shrub will grow 4-6 feet tall and wide, has many prickles and will sucker and form thickets, crowding out other plants. It prefers moist, acidic to neutral, well-drained soils and is poor soil tolerant in full sun. It is also drought and salt-tolerant. Deer tend to avoid it but may eat the flowers. This shrub has become invasive, especially in the New England states, Virginia and parts of Canada, especially along coastal areas. Many cultivars have been developed with single, semi-double, or double flowers in various colors and with fewer prickles. Please choose a cultivar that is better behaved than the species. See a few examples to the left.
