Delicate and resilient at the same time, Rosa rugosa Alba, also known as Shrub Rose Alba and White Japanese Rose, is a vigorous shrub with glossy, wrinkled leaves and elegant white flowers. Rosa rugosa Alba is famous for its endurance - this beautiful rose can survive even the severest European continental climates. Rosa rugosa Alba blooms in early summer through to late autumn. During that period, this medium-sized, bushy shrub produces masses of fragrant, pure white flowers. The flowers are 5-petalled and open, with yellow stamen in the centre. The tender blossom is in perfect balance with lustrous, leathery leaves. In late autumn. white flowers give way to large red hips, similar to cherry tomatoes, and the rich green foliage turns to gold, making these low-growing roses beautiful and noticeable well after the flowering season ends.
