More information
Long John Silver differs from other variegated roses by its size and vigor. The variety grows very rapidly, and large thorns hook onto supports. Flowers are pure white, very full (densely double). They appear in clusters of 3–15 on short pedicels; clusters can become very dense because the flowers remain for a long time without dropping. The foliage is unusually large. Shoots are very rigid and do not bend; the shrub is erect and notably vigorous in growth.
This is a well-known Rosa setigera hybrid. The silvery-white flowers (11 cm) are very double and lightly fragrant. They are borne in large, dense clusters, as the blooms do not fade for a long period. Sometimes blooms repeatedly. The leaves are large, convex, and rounded—a characteristic feature. The shrub has stiff shoots that are bare below and quickly reaches 5–6 m in height.
