Discover the captivating beauty of Rosa rugosa 'Alba', also known as White Rugosa Rose. Originating in Northeast Asia and Japan, this visually striking rose species showcases large, silky and aromatic 4-inch flowers in an elegant shade of pure white, complemented by stunning golden stamens. In autumn, the leaves transform to a contrasting yellow, highlighted even further by sizeable orange-red hips. Rosa Rugosa Alba thrives even in less than ideal conditions, blooming repeatedly in poor soils and coastal locations.
This robust rose is best cultivated in a mix of moist, slightly acidic, well-drained garden loams whilst enjoying full sun to part shade. Even though it perfectly adapts to poor soils, its flowering prowess and behavioral resistance are the most vibrant in full sun. To keep it healthy, make sure to provide excellent drainage, avoid wet soils, and ensure good air circulation.
Interestingly, White Rugosa Rose has a unique characteristic of surviving extreme winter, even with temperatures plunging to -50 degrees F. resistance. It has naturalized in many northeastern and central U.S. states and has often escaped gardens to thrive along roadsides and railroad right-of-ways. It is extremely tolerant of salt sprays and found predominantly near shorelines, earning it other common names like beach rose and salt spray rose.
The 'Alba' variant is a dense, rounded shrub, typically growing 4-6' tall and 3-5' wide displaying fragrant, pure white, single flowers blooming profusely from late spring to late summer. Its glossy, leathery, dark green foliage matures into attractive shades of yellow, orange, and red in the fall. Making it an excellent choice for a vibrant, fragrant addition to your surroundings while aiding in stabilizing beaches and controlling beach erosion.
