Rosa rugosa Blanc Double de Coubert (Rugosa Rose)

Tough, hardy and incredibly fragrant, Rosa rugosa 'Blanc Double de Coubert' is a vigorous, upright shrub boasting a profusion of large, 4 in. across (10 cm), pure white, semi-double flowers (10-20 petals) from early summer up to the first frost. Blooming almost continuously, they are occasionally followed by fruits that are as pretty as the flowers themselves. Resembling cherry tomatoes, the striking scarlet rose hips, provide a beautiful contrast against the foliage of dark green leaves. Cherished for more than 100 years, for the length of its flowering season and the power of its fragrance, this reliable, naturally disease resistant, carefree shrub is wonderful when used as a specimen, flowering hedge or in the mixed border. Place it near a corner where you frequently pass.
