White Japanese Rose is a white form of Rosa rugosa that is native to Japan and eastern Siberia. It is a vigorous growing shrub up to 6 feet in height and has pure white 4 inch scented flowers which are produced from June to September. It is actually one of the few species roses to re-bloom. Blooms are followed by large orange-red hips, many the size and color of cherry tomatoes. The hips are highly ornamental and persist on the plant well into winter, and may be used to make jelly, rose-hip syrup and even homemade wine. Like all Rugosas, these are widely recognized for their low maintenance, pest and disease resistance, fragrant blooms and extreme hardiness.
These make wonderful hedges, look great in a mixed shrub border or grow them as a specimen plant. It is easy to see why Rosa rugosa alba is one of the highest rated roses by the American Rose Society - highly fragrant, disease resistant, winter hardy, easy to maintain, and its wonderful large hips.
